I did my searching.

There seem to be very mixed answers on the issue of a CEL with a aftermarket intake on the new Civics. It's time to swap out my air filter, and I'm throwing in a K&N filter if I'm going to end up with a CEL on a brand new car because of the MAF.

Thoughts/opinions?

 

I'm pretty sure a drop-in filter won't throw a CEL. I have an SRI and no CEL's and I've had it on for almost 20k miles. I think you're good...Hell I don't even have a cat and no CEL lol..

 

Sorry, I realize now that what I typed was a little unclear. I'm sure the drop in won't cause the cel, but wanted to make sure if I dropped the money on an aftermarket intake, I wouldn't end up with a CEL.

 

if you get an aem or the fujita. i think those cause can casue a CEL, but i have had the k&n and now the takeda. I hear good things about the injen as well.

 

sorry I read through your post a little too quick. But I see what you mean now. I have an Injen SRI and no problems at all. Sounds great and also feel a gain. No regrets on my end.

 

My Fujita hasn't once given me a CEL since I installed it nearly 2 years ago. I disconnected the battery prior to install (like most other people have done) and let the car idle for about 15 minutes after the install and haven't had any CELs, bogging, or rough idles at all.

 

So pretty much if you follow those basic steps for installation, mainly disconnecting the battery, you should be good..

 

Do that ^

I did that when I installed my Injen SRI and I never had any problems at all.

 

Can't say for sure for our "picky" cars as intakes are not made equal even with brand name products. I've owned both the INJEN short and the over-priced MR technology CAI version and both have given me a fair amount of trouble (the SRI more so than the CAI). I've driven days without a CEL only to get one out of nowhere. I've triple-checked installation, battery disconnection and done ECU idle runs with no viable long term solution. What's strange is that my friend's fujita SRI ran perfectly fine on both of our cars but experienced the same issue with the INJENs. Very few manufacturers (AEM only) have addressed the disruption caused to the MAF by the increased air flow of the new intake design. Stabilizing fins at the MAF should be the norm for our MAF sensored cars.

EDIT: It's been a few years but if I recalled correctly, the fujita SRI that was used did not have stabilizing fins. New ones may be different? Can anybody confirm?

I currently have a DIY modified MAF housing SRI and would not trade it for anything. Why did you I switch from the CAI? Simple. Throttle response/hesitation. I use my car as a daily driver and I couldn't stand the bog below 4000rpm even though I may have more high-end power.

 

here are some recent posts i made in threads about this sort of thing-

also, somewhat unrelated, but a note on resetting-

I've had the mishimoto in and didnt throw a code till 6 months/10k miles later.
checked the code said i was running rich on cylinder number 4. So you could get an intake and throw a code later on. get flash pro and run map.

 

+1 for injen SRI, 15K miles so far without a single CEL. I also disconnected battery and let idle for 15 min after the install.

 

I have had a AEM CAI for 2 years and never gotten a CEL. My mechanics installed a Wideband O2 sensor (I think) when they did the CAI. Not sure here, but that "might" be why I never got a CEL. I need to check my paperwork. I know they installed a Wideband something, but now that I think about it more, the Wideband O2 sensor might have been for the A/F gauge which was installed much later.

 

Fujita is junk. RICO is one of the few lucky ones. Mine gave me nothing but problems. My car has never run right since the Fujita was giving me problems.

 

Your right Rico, the issue with the fujiti intake is not the cel.

I just looked it up and it was the issue hondata had when tuning si's with fp. The fujiti gave a very inconsistant reading of air fuel ratios.

I think that the best intake on the market is probably the injen even thou I do love my takeda

 

Only intake I ever heard of throwing a CEL was the version 1 AEM cold air and short ram intakes, I ran an Injen SRI for around 30K and a Mishimoto for the last 10K I had the car and never had any problems. I removed the battery during both installs and did the idle for 15 minutes deal the first time, not the second time around. Never had a single problem.

 

a k&n drop in filter wont cause a cel. its the actual design of the aftermarket intake that causes it. like tokyo said the version 1 aem intakes would throw cel's left and right. my friend has a fujita sri, and it wont stop throwing a cel. he'll reset the ecu, and it would go away, but about 100-150 miles later, it comes right back. my injen sri that i had for about 20k miles, never threw a cel no matter how hard i tried.

 

i have the Takeda on my FG2 and no CEL...

 

^^ So you finally go yours in. How do you like it?

 

i sort of want an intake again.
aww shucks

 

Why'd you get rid of yours in the first place ivtec?
