Well, I suppose its gonna vary from vehicle to vehicle, but I just installed my AEM CAI on my 94 LX and I definitely noticed a performance gain, especially in the high end.

 

:werd: you also get what you pay for

i'm happy with my Injen CAI and Greddy setup, i wonder if DC sprts 4-2-1 headers would make a difference?

 

Two words again: OBD I

 

You guys and this ecu reset deal is cracking me up. The ecu resets every time you turn your car on. I have heard sooo many things from taking your hazards fuse out and putting it back and waiting 10 minutes at idle to disconnecting the battery, that to me is all funny considering people think it actually does something? Basically if you want power or improvement whatsoever do not buy an intake and expect to be faster. It is basically a bunch of noise and maybe (i stress the maybe) a horsepower gain but no more than about 1-3. Go pay for something that actually improves performance, possibly a high flow cat with full 2 ½ inch exhaust set up with a header? By the way i have a DC header for sale from a 90-93 accord f22a1, anyone interested PM me

 

No...there CAN be a significant HP gain. Modifications build upon each other... although I would do...(in this order) exhaust + header (if you can afford it), THEN intake, then other mods. And by the way, just b/k a part is 'so-and-so' doesn't necessarily make it good. I've seen some 'name-brand' headers make stock hp on some applications. I'm talking like no more gain than 1/2 a pony.

It's just that with newer cars and OBD II, they...well...suck from a stock modding standpoint. Very little can be elicited for the most part from a "bang for the buck" standpoint in post 95 cars. (Unless you run an aftermarket engine management system like Tec-II or Motec or Haltech - whatever)

On older integras 90-93 (and i'm recalling this from memory from old HKS catalogs), HKS exhuast + HKS Powerflow intake yielded an additional 11 ponies. Now, I'm not sure where in the powerband those ponies were occuring (never say dyno charts), but in an integra of the time, you absolutely and positively could feel a huge difference in the seat of your pants. And it wasn't the loudness either. What's going on with the V6 accord is OBD II forcing the car to work within preset parameters. I've seen dyno charts of OBD II bmw's w/ performance everything. The only things that actually made a difference on that car was magnecor plug wires and Redline oil (throughout the car: steering fluid, tranny fluid, rear diff, engine oil). The gain on one car (97' 318ti) was like 5.6 or 5.6 hp over stock for those mods. The exhuast and intake they put on actually made LESS hp than stock. I'll try to find the OBD II explanation post I made a year ago....

 

OBD II cars that DO respond well tend to be the DSM's...turbo eclipse/ others that run that motor....etc...

Oh, and reseting the ecu can make a difference...depending on your car, your ecu can "learn" the style of your driving.

 

I personally think icebox is the biggest waste of money, it's pretty much like a stock intake w/o the resonator. Is your car 6gen v6? if so try the injen cai, I feel a lot of differences with it.

 

Import Tuner
6 Gen V6 Accord EX

AEM CAI = 6HP Gain
Greddy EVO Dual Catback = 10HP

pretty good gains if you ask me

 

azn-good point, dynos cant go wrong

 

one of the things I've always wondered is whether or not the car Import Tuner (or X magazine) is using (remember, parts and the car's time is usually donated), has been set-up with an aftermarket ecu. It wouldn't be a lie to setup a car with a different brain, dyno it and present it as a car with 'such-and-such'. They told you what it had. They don't tell you what it DOESN'T have.

If you look at the relationships magazines have with product manufacturer's who buy ad time...has there EVER been a time when something was presented with a negative overall 'official' magazine opinion? Perhaps not so much lately with SCC (since they've gotten so big now) but smaller mags like Import Tuner and Super Street...well...there's always an agenda when it comes to advertising and DOLLARS.

I sometimes find numbers like these "dyno" numbers hard to believe...especially when OBD II Hondas are presented as making as much gains as their OBD I brothers (i.e. same kind of general engine config...etc.)

Anyway, here's that OBD II thread I wrote-in a while back...see some who put on intake and got JACK **** for RESULTS. Of course, your results may vary...

fyi: somebody else's scientific post in an IS300 (Inline 6 ,215 hp, auto)

Please excuse this extremely long post:
I installed my Rod Millen Motorsports (RMM) Intake system today and i also installed a 75hp NOS wet system. I went to Moroso Raceway tonight to see what the improvements would be and here they are. First are my results from when i took my stock IS300 to the Moroso Raceway 2 weeks ago
when the car was completely stock.
1st run:
launched at 2000rpm
60'---2.357
1/8---10.294
1/4---15.893
MPH---86.23
2nd run: lauched at 2500rpm and took out the air filter.
60'---2.333
1/8---10.219
1/4---15.817
MPH---86.72

3rd run: lauched at 2500rpm wo/air filter and lowered the tire pressure to 23lbs.
60'---2.328
1/8---10.234
1/4---15.803
MPH---86.68

Now that i have installed my RMM Intake system i can honestly tell you that i looks fantastic!!! Nice sound to the engine when give throttle....BUT.... i could tell from the get go that the car was noticably slower on the low end. Felt as if was loading up.
I thought that i might just be my imagination but my fears were confirmed at the track.
Here are my first 2 runs:
1st run: Launched at 2500 rpm with the track off and the ETC power on.
60'---2.436
1/8---10.604
1/4---16.298
MPH---87.04
(as you can see i lost .495 which is almost 1/2 seconds slower than my best time 2 weeks earlier but gained .32 in MPH)
I thought that maybe i did something wrong so i check my notes and ran the car a second time to confirm:
2nd run: launched at 2500 rpm again with the track off and the ETC power on.
60'---2.457
1/8---10.571
1/4---16.248
MPH---85.81
I could not believe my f@#%ing eyes!!!!
I lost .445 seconds in the 1/4 mile.
The car felt so slow at the launch... i could tell it was not good. The car really started to excelerate hard high into 3rd gear. To me the air sensor is telling the computer that its getting most air and it either sending more fuel or retarding the trottle???? i am at a loss!

I thought to myself that at this point lets make a run with the NOS. NOS jets: fuel #37 NOS #45
!!!!!!!!!!!!!!!!!!!WOW!!!!!!!!!!!!!!!!!!!!!!!
1st run: launched at 2500 rpm with the track off and the ETC power on. I hit the NOS once i launched off the line so i would avoid tire spin. I had no tire spin at all.
60'---2.282
1/8---9.615
1/4---14.786
MPH---95.17
Holy ****!!! i gained 1.422 second that almost 1 1/2 seconds off my best time of the night and gained 8.13 MPH!! Very impressive.
2nd run: all the same as above:
60'---2.304
1/8---9.648
1/4---14.819
MPH---96.43
This time i felt the car studder at the top of 2nd gear.. but then hit hard again. Thie 1/4 mile is a little slower than the 1st run but my MPH was better.
3rd and last run: Launched at 3000 rpm with the track off and the ETC power on and i decided to hit the NOS button right at launch. The car took off like a rocket with only a little tire spin.
60'---2.230
1/8---9.449
1/4---14.723
MPH---90.33
As you can see all my times were better except my MPH...i had to let off the NOS at in the middle of 4th gear as the car started to fall flat and studder. I think this might be from a lack of fuel at the top end.

I am very disappointed with the RMM Intakes performance... i lost almost 1/2 seconds in the quarter mile. I spoke to other IS300 owners who have the exact same feeling of the RMM's performance. I think the RMM Intake looks fantastic and sound great but i would rather have performance.

I can't figure out why the car has slowed down with just the RMM intake?? When i hit the NOS it feels as its starving for fuel..so if i lean it out stock i will be even worse on the NOS!??? what to do??
Any feed back would be greatly appreciated.

I am going to re-install my stock intake and install the NOS into that and give the track another few round and keep you all up to date.
