wow, the tone on my exhaust and the sound of the car completley changed. I was amazed. Install wasnt that hard at all, instructions were awsome.

 

Congrats, once you start doing more mods yourself you'll come to find out everything comes second nature basically.

Love the KnN on mine. The tone just rocks! Keeping it going with the DIY. Nothing better than doing the work yourself and if you get stuck this forum and the ppl here are awesome at helping you out.

 

I have the K&N and I think its a POS. Made my car perform worse.

 

ANYWAY!
good job dude. now get that aem bypass put on and take off that rain protector and u will b on point. rain protector restricts airflow. enjoy

 

Sorry I had to be so negative, but the fact is the K&N is a very bad intake for the tC. It is dyno proved that the K&N does about nothing. The powerband is no where close to linear. I am not being biased as most of you who have the K&N would be. I actually have a K&N and I think it just a substandard product. Injen CAI proved it is the superior product and actually gained a fair amount of power also had a linear powerband curve.

 

though it may seem like it, most good rain/hydro covers do not restrict airflow much and if any, it's insignificant.

 

Are you positive? Cause i thought they both made similar gains, i mean come on its a tube with a filter at the end near the bottom of the car to get some cold air...lol

 

That is true, although injen spent a extra year in research and development. There is hard evidence that the Injen performs much better. K&N just made some POS and put it out on the market as fast as they could.

This is taken from Monsterworks research on intakes..
third K&N Typoon intake
The air Fuel got a little funny on this one. could be the cause for less HP than the others. With the cost of the intake I think your money would be better spent else where.

Stock intake gives 149.41Whp and 157.98lb torque.
K&N gives 152.90 WHP and 159.65lb torque.
Injen gives 157.50 WHP and 162.28 lb torque.

K&N yields 3.49 WHP and 1.67lb of torque over stock but wierd air/fuel ratios. (I don't know about everyone else but these seems pretty bad for 250 dollar intake. Especially if its messing up air/fuel ratios.)

Injen yields 8.09 WHP and 4.3lb of torque over stock. Now to gain 8.09 WHP with just a intake is amazing. It is obvious that Injen is the superior product and actually put thought into making their intake.

 

I've run the K&N CAI on my tC for about 10k. Although it has a cold start lag at 1st, OVERALL it's a good DIY MOD. Good choice IMO. I think it has the best growl of all the CAI's. Once you add a nice cat exhaust you'll really appreciate this MOD. GJ and enjoy.

 

i'v read that aem's air bypass valve restricts a small amount of air on a part description paragraph...so the rain cover is cheeper

i have a K&N on mine and i am completely satisfied, also i think K&N themselves rean a dyno with it to show a 6 to the wheels gain.

 

K&N did do a dyno themselves but that does not truely show what it is capable of. What mosterworks did was the same tC with different intakes showing the actual gains. Also I perfer performance over a nice growl anyday. Usually K&N is top notch for their intakes but it was just rushed on the tC.

 

now i'm sad, i'm looking for performance over sound aswell but injen specified that thier intake was for a 5-speed (i have an auto) so not really knowing i went with the other big name that didnt say it was only for a stick....does it matter anyway?

 

Yeah that 5 speed thing doesn't matter. I got a auto myself. And since we're both autos I bet it hurt our performance than anything. If the manual only gained 3whp and 1.5 lb torque umm auto probably got negative gains.

 

cai sucks on auto tcs. thats interesting. i have a manual with up- grades. i rest my case. dismissed

 

Well I realized how bad the CAI sucked on my auto tC so I decided to mod it to my own specs. I took the stock intake box and just connected it to the other half of the K&N and I got all my torque in the low end back and still have colder air coming through. It also flows better because there is no more air filter except for the K&N filter at the end of course. I had to compromise because I did lose a bit of top end that the full K&N CAI provided but at least now I have a power increase throughout my whole powerband.

If you're an auto you lose gas mileage because of CAI's. This is because you lose so much torque in the low end that it takes more power to move the car. So you're reving your car higher to just get it moving.

 

hey i have knn and i drive a stick.. i thought cai are suppose to provide better gas mileage??? but it seems in my case it went worst.. im getting only 250-260 on a full tank.. thats only 20mpg... thinking of replacing my knn with injen... or the new fx1...

 

CAI on any tranny isn't going to cause a loss of tq that great to really "suck". Also, CAI doesn't improve MPG but maybe 1mpg more. Its not enough power increase to do that, its just a step 1 of three to get the motor breathing right.

your engine can only breath as well as its most restrictive part will let it so you are correct

 

I know i am. Jk, well, i know i wasn't lying but i didn't want to sound too cocky.
