There seem's to be an ever growing amount of new threads with intake questions that have been answered on here a million times before. I am creating this thread to try and shed some light on the topic. Please feel free to add anything I forget. Once complete we can have one of the mods lock it down.

Question 1: What intake should I buy?

Answer: There are alot of company's with intakes on the market for our cars. The list go's like this: Injen, AEM, Fujita, K&N and Weapon R. It seems like the Injen CAI is the most popular with the Fujita short ram bringing up second. The AEM initially had alot of problems with throwing a CEL but they seem to have fixed the issue.

Question 2: Will an intake void my warranty?

Answer: As with all aftermarket prooducts, if the dealer can prove that the problem was a direct result of the modification, then your warranty claim will be denied. Pretty much the only time your warranty claim will be denied using an intake is if you hydrolock the motor (covered below). If you have any doubts on this, google the "Magnuson-Moss Warranty Act".

A dealer has no authority to void a warranty just deny the claim.

Question 3: Will a CAI cause me to hydrolock my motor?

Answer: There is always a possibility of hydrolock when it comes to Cold Air Induction. In order for this to happen you would have to drive through a pretty deep puddle and completely submerge the intake filter. At that point the CAI will act like a straw. See Below...

Question 4: Does a short ram suffer from heat soak?

Answer: Yes. A short ram pulls in the hot air from the engine bay resulting in some degree of heat soak, although I think this will be debated until the end of time.

Question 5: Is there an intake bypass valve out there for my CAI?

Answer: As far as I know, not yet. Your best bet is to search each company's website and see if they make one. Here is a link for a DIY if you want to do your own http://www.8thcivic.com/forums/showthread.php?t=26334&highlight=cai+bypass . Injen has the hydro-shield which is a cover for the filter, but I'm not sure how well it works.

Quesiton 6: Do I have to pull the bumper to clean my CAI filter?

Answer: No. It is not neccesary to pull the bumper off to clean the filter. With this you have two options. You can A: pull off the wheel and peel back the splash guard to access the filter or B: you can pull off the bumper and access the filter that way. It's up to you what you do. It all depends on which way you think will be the easiest.

The following dyno's have been posted by 8thcivic.com users:

*Snoopy*


Fujita SRI and Hondata IMG

*HAQER*


AEM CAI

That's all I have for now. Feel free to chime in and I will edit the thread accordingly.
Must pull bumper to clean filter for CAI

Must pull bumper to clean filter for CAI

I'm not sure if that's absolutely neccesary. I know with the CAI I put on my LX, I could get to the filter by pulling the splash guard and reaching in. I haven't put a CAI on my Si yet so I'm not sure if you have to pull the bumper to get to it.

Can someone else varify this?

I know this is a bit late, but ironically I started reading these threads AFTER I installed my Fujita F5 SRI last night (11.29.07) on my '07 Si Sedan. No CEL, no hesitation, great sound, increased power (yes, my ever-skeptic mind has been won over), etc. I can see why it's rated so highly. Great thing it's cold outside in Southwestern PA these days - it helps with that whole heat soak thing, but it's better than the hydro-lock worry with CAIs, imho. It rains too much in Pittsburgh. LOL

OK. But i have read that you need to cut it to allow the fit of the injen CAI. That would defeat the purpose of it right? Water will go straight to it.

I understand the bypass but that is only good if you completly submerge the intake. Image the amount of water it takes for you to hydroplayne (sp). Will that sudden splash get through the filter?. I assume that little amount will cause white smoke.
That little amount of water will more than likely just evaporate given the high temperature of the motor.
