i've been thinking... if i remove the stock intake box and everything, what do you guys think of getting a K&N custom sized short filter and attaching it directly on the TB? for example, i think a hks style foam filter will fit, but i'm not a fan of foam filters. anybody have any comments on this? i am considering this b/c of the cost, and it might be comparable to a sri.

BETTER OFF WITH A COLD AIR OR SHORT RAM TO GET AWAY FROM THE HEATED AIR AROUND THE ENGINE

it would only work good with a hood scoop and im not sure if you want to do that lol

Uh, how are you gonna hook up the O2 sensor?

No O2 sensors hook into the air filter.

The only problem that you are going to run into is finding someplace to mount the AIT sensor into the filter at. But with some ingenuity I'm sure you can easily come up with something like that, I think it would be cool to see it and it might actually be nice considering the heat value near the TB is almost no different from where a regular Injen SRI sits.

oh, that's right. i forgot about the O2 sensor. I guess I was thinking about my accord instead of the civic. hehe. but i'm sure i can rig up a bung for it. anyhow, thanks for the comments. i'd think it'll be like the sri and cheaper, so that's why i was thinking about it.

02 sensor... are you guys nuts??? stop being ghetto... doesnt pay in the end....

just had to write twice cause o2 sensor on intake is HILARIOUS

only thing is with no piping you will have like no low end. might not be bad for top end though.

Why would no piping on the intake result in no low end?

i already have a AEM CAI in my accord, but i was just looking for a way to make a cheaper and effective intake like i did for my mom's caravan. and yes, you can feel the power difference between the stock and my ghetto rig up.

you're going to lose low end.

why? cuz you're stuffing air in without carefully considering the impact on air velocity across the powerband.

and the air temp sensor can still be plugged in.

it works okay for ur caravan because the stock system was already quite short and you still have some stock tubing going on there... although I bet you still lost some torque right there, but you probably can't feel it on the butt dyno cuz it already had some amount of torque already.

honestly you should probably take that intake off the caravan.. yeah maybe you've shifted the power upwards to the powerband, but you're going to lose the intended torque the van needs, you're just wasting gas and losing mpg... and its a van dude.

thanks for the input capyoda. i just had a case of the mod-bug for my mom's caravan. haha. i'm probably still going to keep the filter on the caravan cuz of my buttdyno results. i'm still deciding on the civic cuz the fipk is just too damn pricey compared to my accord's aem cai. $230 for a short ram and heat shield isn't cost worthy in my eyes. maybe later i guess. perhaps i'll look into the injen one

I'm not sure I agree on the shortened intake affecting torque. Maybe on the runners, but not beyond the plenum. The intake runners can have a serious affect on intake charge tuning. But beyond the plenum, you're just supplying air, not working on harmonics.

when you say beyond the plenum do you mean beyond the tubbing? or beyond the throttle body or intake manifold.

i'm always under the impression that the length, diameter, and bends of an intake tube plays a certain part to the tuning, even if its small part in our case.

i could be wrong though.


i probably shouldn't have stated that for the caravan though since I'm generalizing a bit there. since usually when you stuck an aftermarket filter on an engine, there's a shift to the righth for the powerband. and yeah that doesnt necessarily mean the tube length has anything to do with the change in power, just the difference of air in at different rpm.

anyway I woulnd't recommend the InJen SRI... I had it and it honestly wasn't a R&Ded product.

the FIPK is quite expensive yeah.. i bought it used though for around 140.. so if you look around it may be okay.

although 140 for an intake is still expensive... with the fact that it doesn't really do anything but make noise. heh.

I just have a question that I've been wanting to know for a while because I dont even know, here goes, Is a sri better than a cai or is the cai better because when I took my car in to get serviced like a while back a service adv saw that I had a cai and told me that the sri actually puts out better than the cai because the piping on our intakes are tiny and not big so it takes longer for the air to get to the TB rather than a sri would? Is that true because it sounds pretty believable to me?

Just stop being lazy and do a search. That topic must have been covered like a billion times
