So today was mod day for my xB. I installed a Fujita intake, Monroe shocks, Progress rear sway, and homemade pollen filter. I love the shocks, sway, and filter. Not sure on the intake so far...

Installation... I thought it was unnecessarily difficult to install in my 06. The wire from the wiring harness for the MAF sensor seemed short. Same for the wiring for my driver's side headlight so it took a little patience to get in position. Had to tweak the included solenoid bracket for it to work. The rubber hose piece that joins the intake to the throttle body seems like it should be longer since the two aren't perfectly aligned. Nothing major, just a few annoying things. I'm never going to want to take this thing apart to service the filter.

Driving impression... Ok, so the power gain is definitely noticeable. Seems to start a little over 3k and build from there. Also, now my xB is rev happy. With the stock intake, it didn't freely rev and didn't really want to go much about 4k. Now it'll rev 5k+ without complaint. Very small increase in noise level.

The problem is that it seems to have lost a little bit of low end torque. There wasn't much to begin with, so losing any is noticeable and annoying. I found myself driving about 500-1000 RPM higher than I was without the intake. Part of that was because it was new, the other was so I'd be in a range where it would pull. Only one afternoon of driving, so I'm going to give it a month or so to see if I can adjust. I'd just really hate to give up the city drivability for a little power gain on the top end.

 

Sorry to hear that you're a little disappointed. Let us know if it starts throwing any CEL's.

 

Don't think it'll give any errors. I drove about 75 miles after installing it so I'd expect one by now if it was going to cause a problem.

Since the usual response to "i want more power" is to "install an intake", I just wanted to throw a post up letting people know there is a possible downside. Like I said, I'll give it a month or so to see if I can adjust. Maybe the computer has some learning to do too.

I do like the added top end power. It gives that little extra boost for passing. I didn't think I'd ever pass ANYTHING with my xB. I can also now see how some people have no problem going faster than 75-80 MPH. With the SRI, it'll rev freely past 4k where the stock intake seemed to choke.

 

keep us posted, because I was looking into the fujita cai, everything I've heard/read about AEM is they are junk, and 400 for the one from the factory is just too much

 

I would think the lack of low end power would be even more noticable with the CAI.

 

well I drove the dealers xb before mine came in, it had the AEM cai, and it seemed to have a little more get up and go then mine, but mine is all stock, theirs had the CAI and the TRD cat back

 

I thought the CAIs will give you less hp, but don't give up as much torque. I got the SRI because less chance to suck in water (bypass on the AEM CAI), it's out of the way so it can't get damaged, and lower cost. There's AEM CAI on eBay for pretty cheap- they're yellow and include the bypass for $201 shipped.

I specifically chose the Fujita because the oil vent from the valve cover is after the MAF sensor. All the other SRIs have the vent attaching in front of the sensor so it's possible oil mist/fumes could contaminate it. My 2nd choice would've been the K&N because I had an intake from them on another car and that was a quality product. Also, the K&N comes with some sock thing over the filter which they claim helps shed water.

I just got back from a couple short drives. The torque loss wasn't as noticeable as when I first installed it so maybe it was a computer learning thing. It's also about 20 degrees cooler than yesterday and raining so it's not a totally fair comparison. I had to put the vent on defogger mode and I think the extra hp helped compensate for the drain of the A/C compressor.

 

CAI should net more hp because they drawn in cold air from outside the engine bay. However, they will lose some low end torque because of thier length. It's a trade off. Short intakes and cold air intakes are very similar to 4-2 headers and 4-1 headers. One gives you more on the low end, the other gives more top end.

 

samhain is correct.

with the CAI your power up top will be better but low end will suffer some. with a short ram it will give you more low to mid range but top wont be as good.

is there any companies that make an intake like the comptech for xb's? i had one on my older civic and it gives you the best of both worlds. its a short ram with a cold air extention so it pulls cold air into the short ram.

also maybe you might want to try ditching your homemade filter and picking up a k&n one instead.

 

are you saying that cai takes a torque hit compared to a sri or the stock intake as well? Ive been running an ebay cai for 2 weeks and i love, better sound, and upper end power,2700+, you can really feel. best 50 bucks i spent on my car

 

Just a follow up after having driven a couple months and few thousand miles with the Fujita SRI installed.

Definitely much better at higher RPM. The extra power makes freeway driving and passing easier. I got cruise control installed after the intake and I think the few extra HP from the intake helps maintain a constant speed on moderate hills. It's more of an issue for a manual since pushing in the clutch to downshift would disengage the cruise.

Still noticeable power loss at lower RPM. It's not too bad though. Just don't try to drive "normal" and expect to beat anyone off the line from a stop. No problem driving in bumper to bumper.

As I said in my first post, the install was a little tricky getting everything to fit and line up. Now the MAF wire doesn't seem that short. Maybe it pulled some slack out of the harness or something. No apparent leaks where the intake connects to the throttle body. There's at least 3/8" clearance between the battery, MAF and intake mounts. No error codes. The filter seems well protected so I'm not that nervous about driving in the rain and possibly hitting a killer puddle now. No change in gas mileage. Noise increase is insignificant.

If I had to do over, I think I'd first try a drilled out stock airbox (an extra one from a junkyard or online) and a K&N drop in. Not because there's really anything wrong with the intake. It'd just be nice if everything were in the stock location. It's going to be a pain cleaning/changing the intake's air filter- total uninstall and reinstall. Also, it has been my experience that the dealer will blame the aftermarket parts if there's any problem with the car. With a modified stock airbox, I don't think they'd question the stock airbox even if it had some extra holes in it. I know I wouldn't have gotten the same 4-5 HP gain the intake provides, but I wouldn't have lost much low end either.

 

Interesting. I'm still on the fence about purchasing one. Thanks a lot for the follow up. The good news is no CEL codes.

 

nice update. I was planning on installing my Fujita SRI 2morrow since I had an extra personal day to use at work. I was prepping my stuff 2nite, and when I went to mount the filter to the pipe, it wouldnt fit. Finally realized that I received a 2.5" filter when I should have received a 2.75" filter. No wonder the filter wouldnt fit on the pipe. Hopefully Fujita will rectify this issue since many have posted that the quality of the Fujita is top notch.

 

Same thing happened to me! I bought off eBay and the filter was a 2.5". Took about 20 minutes of trying to jam the thing on before I looked at the part list and saw it was wrong. Call Fujita ASAP. They'll send you the correct 2.75" with a return UPS label for the 2.5" that came with your intake. Not like the 2.5" is any cheaper so I don't think the eBay seller swapped it. If you're hell bent on installing it, you could always hit the local auto parts store for a similar size K&N or knock off. Cuz it'll take a week or so to get the replacement.

For the install... it takes a little patience getting the filter through the wiring and under the headlight. Also, you'll need to bend the included bracket and possibly enlarge the screw hole if you have a 2006. The hose clamps to attach to the throttle body are too big so you'll also want get them started before you put it in. And make sure you put them in as shown in the pics. I put mine in with the bolts on the other side and had to swap them.

I do think the Fujita SRI is the best SRI available. Mainly because the crankcase vent hose is after the MAF, like the stock intake. Everything does fit well and you do get a 4+ HP gain over stock. It's just more of a dog below 2500. I'm addicted and won't give it up until the filter needs maintenance. Then I may try a drilled airbox or something else to see if it's acceptable. With the SRI, I still do have a small fear of hitting a puddle and hydro locking if it's raining really bad.

 

I passed up on Fujita and went with a Blitz Induction Cover and a lot of people here dismiss it.

But you do have torque and pep! I liked the option better than swiss cheesing an old air box because the air flow into the filter is completely open on the bottom and the hot air arguement is silly cause the car is moving and there is no obstruction at all.
No traveling.

Some peopl bad mouth it because you really can't see it except fot the BLitZ emblem on the air box but it fits perfect and it holds up the top of the box with two metal arms.

When I got the DC Sports exhaust I lost a little pep but it seemed very powerful on the highway.

Prior to the Blitz I had a generic intake and it wasnt very good.

The Blitz was nice hardware and filter and fit perfect. Real easy to instal compared with the pipe.

 

So how is the top half of airbox mounted with the Blitz? The bottom half of stock box has 3 bolts through the bottom. Take away the bottom and where's the support?

The only "problem" with the Blitz is the cost. A lot of people didn't want to pay $120 for a frame and filter. In theory, you could make the frame from $10 worth of hardware store parts and use a $30 K&N drop in. I'd be inclined to buy the Blitz to save the hassle though.

 

I gotta find the old thread of me being walked thru it.

It's 2 L bar type things.

I mean, I guess I don't see why $120 bucks is such a big deal for a nice little item.

I get the arguement and doing what you are saying would not be crap nor is the Blitz crap. Some dismis it completely. THe blitz is still more liberated, though.

And its JDM. Some people liked that. The instructions were in Japanese too.

Nice. I just started thinking about when reading the thread from cliffy1 about the dealership not liking a customer's intake. Starting in 2006 there is a charcoal filter built into the top airbox. So replacing with a SRI or CAI removes a piece of emissions equipment and the reason there aren't any CARB exempt intakes for the 2006+.
