View Full Version : Does the TRD CAI interfere with battery removal/install?

I'm considering adding a CAI to my 2008 xB (just picked it up last week.) From looking at online photos, it appears to me the TRD CAI throttle body to filter pipe passes over the negative battery terminal. That raises the question of whether the battery can be removed and installed without partially dismantling the CAI.

Could someone with experience with the xB TRD CAI please tell me the answer?

Thanks !

PS. I asked at a Toyota/Scion Service Center and they didn't know -- seems they've only installed the CAI on tC's, never an xB.

well you need to remove the battery and remove the battery tray cause you will need to place the intake under the battery tray and then put back the battery and relocate negative post

Thanks, but I'm not asking whether the battery needs to be moved in order to install the TRD CAI, I'm asking whether the CAI needs to be moved in order to remove/install the battery -- something that could well be required at some time after the CIA installation.

You probably will need to remove the main CAI pipe to remove the battery at some point in the future, but it would consist of loosening two hose clamps (one at each end) and unpluging the mass airflow sensor. It won't even take you two minutes. No worries.

why are you worrying about replacing the battery? batteries lasts at lease 3 years, up to 5 years.

start worry about cleaning the filter. filter should be cleaned every 3k miles.

Brother, I would check your figures. The TRD CAI element does NOT need to be cleaned every 3k miles. Try 50,000 miles, or 30,000 in dusty areas.

And I wouldn't qualify his post as "worrying". He was looking for info, and he came to the right place.

30k to 50k... you're out of your nutts. :rofl: even oem air filter should be cleaned every 15k.. what makes you think that trd filter that sux air straight from the outside, needs to be cleaned every 30k to 50k....

You're right. I'm wrong. What do the Toyota engineers know anyway.

I recommend page 14 of the install instructions.

the filter is from k&n. toyota didn't made the filter. toyota gets the information from k&n. And you're right, k&n states that the filter should be cleaned every 50k/100k. But the filter is cleaned 50k for stock air box k&n filter, which is not expose to outside air. The TRD cai gets the air straight from outside, which will get dirtier than filter that's inside stock air box. so with that said, 50k filter inside stock air box should be dirty as 3-5k filter that's been sucking air from outside.

Brother, that's a completely speculative argument you're making.

My point still remains. The TRD CAI instructions specifically spell out the cleaning interval of 30K or at least every 50K. How can you go wrong following the engineers recommendations?

hmm...

let me give you guys an example.

There are car A and car B.
Car A is washed & waxed every once a month. Car B is washed & waxed every three months. now, which car would still shine like new car after 3 years? this is the exact point i'm trying to make here. yea you could drive without cleaning the filter for 50k or even more... hell, some people install direct port intake and drives the car without any filter. the filter will be harder to clean and it won't look the same as new. the duralation of the filter is very good, but the oil just doesn't last long as the filter.

washing the filter frequent will help maintain the filter like new.

Well........I think that's another apples and oranges comparison.

You're more than welcome to follow a more frequent service interval. Heck, you can even change your oil every 1K-2K miles. Will you be doing more harm? No. Whatever floats your boat. But please don't scream blasphemy when following the MANUFACTURER's service intervals.

Anywho, I'm off my soapbox.

no, but it a lot of work to clean the filter.. especially when the filter is inside the fender liner...

i have no idea how this thread got off the track...

anyways, i'm a clean freak(i wash & wax every weekend), but you seem to be... Conservative..

i don't know how long you had your cai, but i dare you to compare yours w/ someone who has stock intake filter with double the mileage. you'll know what i'm mean...

no, it just lifts right out. You wont need to move anything
