the problem with CAI's is that if you have 10 different ones, 8 are junk, 1 gives a mild gain and the last one gives you a real, significant power increase. the problem is that there is alot more cheap, innefective parts on the market than there are quality ones. they are not overrated; the bad parts have alot more exposure than the good ones. p.s. i've got a turn2, the good one. makes real, actual, measurable power

I hear Turn 2's are awesome and all, but in the end, a CAI is a CAI is a CAI. How can one put out different power than another? All CAIs for this car go down to where the canister sits with a filter at the end of it. See what I'm saying?

I responded to your other post at the bottom of page 2 by the way.

the difference is in the filter quality and the surface area. for an example, i remember a couple years ago a magazine did a dyno test of like 8 different cai's for the rsx-s. the best WHP number was 18 from aem, the second best was injen at like 12, and the rest were all around 6whp. same car, same dyno, same day.

now the rsx is different from our cars in that the intake makes some crazy bends to work its way form the filter to the TB, so pipe comes more into play than on our cars where it is basically straight. besides that, its just like any other part, springs, chips, etc. some are designed better than others. but there always seems to be more of the cheap stuff than the good stuff.

p.s. nice times

Just did it 5 min ago....hands down alot more noticeable performance than any cone filter....and the sound is incredible...it makes your vr6 sound like a small block v8. Modified by SouthFl VW at 6:43 PM 9-25-2006

then you havent heard a small block v8. cause they sound nothing alike. if my vr sounded like a small block id be worried about the timing.

it does make it sound a hole lot better. and its much better than the cold air that i had on.
my dad thinks it sounds like a vacum cleaner when he drives it, he does think its better than the cold air. noise is supposed to come from the back of the car not the front, so thats what it does better then the CAI.

[BGKid]

any gains on a 2.0? anybody actually know that it bumps up performance, or does everybody just "feel" it.

also for the guy getting a weird idle, try to disconnect your battery, so to reset the ecu.

[piran21]

This made a noticeable difference for me. I have a VR6 and switched from a P-flo type intake back to a modified box w/Fram paper filter and none of the ducting these guys have done. The intake noise is reduced but still there. Throttle response is better and highway acceleration seems a lot better, but I'm not sure. Most likely getting it dynoed tomorrow.

If you can find a K&N to borrow for this dyno, that would be appreciated so we can see an even more realistic dyno difference over the p-flow. was your p-flo with a heatshield or no? if not, i don't have a question who's dyno'inig more, but even it were, i'm still confident.

[piran21]

No heatsheild. I had PCV tubing just bringing the filter to the fender as far away as possible from the motor. I think the air box will be better.

[yo vanilla]

the air box is definitely better than an open element (inside the engine bay, especially with no shield).

and of course i'm sure most people know this, but a short ram is different than an actual cold air intake.

[oempls]

definitely gonna have to do this!

[12w0]

the air box is different on the vr than the 2l right? may someone post a pic of this "mod" done to the 2l airbox?

[cramerica]

the airbox may be different, but its the same idea. improvise

[Fjr17]

I have a question... What if instead of using a panel filter, I use a cone filter?... Does it even fit inside the airbox, and is the cone filter even better than the panel?

how different? would someone who's had no experience (me) be able to figure it out using the DIY on pg 1?

thanks

[UberDub15]

nice

i had already thought of this idea in the past just out of curiosity as well. it does not fit and even if it did, i'm sure the panel filter will provide better overall performance anyway. there is more surface area with a panel filter.

Thanks..It looks like I'll just be buying a panel filter and doing this mod..

[Trixy]

This is what I did with my air box.
aluminum air box with round filter inside
and 3" aluminum flex tube running from the air duct in the front bumper. before this setup, I had the snorkel on the stock box turned around with a tube connecting it with the bumper ducts.

[Dan J Reed]

Daym, is that a FLOMASTER?!

[Slow Jet]

Very inventive. I like.

[azn]

damn awesome!

[botkiller]

what about doing this mod to a 97 jetta trek 2.0 ? seems like the airboxes are the same - and I wanna do some mods for sure.

[$cash only$]

I just did this recently and can def feel a difference because before the air was just trying to squeeze through that small ass tube that was only like 1-2inches if that. With this mod now it gets whatever it can grab. As for sound at WOT i've made heads turn left and right and them honda guys would ask what kind of exhaust i have

[LP_sk8er]

I just did the mod today exactly as in the pictures except I left the honeycomb in place. I went from a short ram intake with no heat shield to this and I love it. The sound is pretty much the same but the throttle response on the lower rpm's is much much better IMO. I am still using the stock paper filter cuz my K&N is being shipped, I hope it makes even a little more response with the K&N

Thanks for the great post Breezy!

it's just an airbox hahaha.

[The Gloves of Death]

I switched from P_flo back to this and like it a lot better.. faster throttle response and acceleration IMO (butt dyno of course)

The 2.0 and vr6 filter are the same so im guessing the boxes are relatively the same.

[d3v5o]

will i notice a sound/performance difference without removing the middle muffler?

[just-a-ginster]

you will def feel a difference

the sound it produces is truely one of a kind

my next mod is the suitcase delete. well see how that sucker will sound then

without a doubt. that deep sound you are hearing in the videos is all motor (airbox/intake).

it will sound exactly the way my car does in those videos i posted on the original post.

[just-a-ginster]

i just need to drop in a k&n

[me=mk3]

Will this work with the stock, paper air filter? Does it make the nice sound without a k&n?
