which is beter the 1pc. 3in dia. AEM cold air intake
OR
the 1pc. 3in dia. by Injen.

That and how much more performance will I obtain in comparison to the stock 2002 TL-S

 

I think both give the same performance boost, about 1-5 HP at the very most! As for AEM or Injen, I think the only difference between the 2 is the amount of noise it produces.

I can't comment on the injen, never had one, but I do have the AEM and it's loud only when vtec kicks in. Even then the noise isn't that much.

 

Well, I'll comment on the Injen and tell you that the Injen sounds the exact same as the AEM... you only hear it when VTEC kicks in. On the highway, just cruising, the car sounds stock. I had a Weapon-R short ram in my CL and it was the same thing, so I think that it's pretty much the same across the board.

Personally, I went with the Injen just b/c of the price. I mean, they do the same thing, produce the same HP, why shouldn't they cost the same? Plus, I think the Injen Blue matched my car better then the AEM blue!!

As for the HP gains... do a search, but there are dynos showing 6 hp at the wheel, which is about 8hp at the crank which is about right. Some manufacturers claim around 10-12hp, but that's very optimistic. You'll see an average of 4-6hp at the wheel gain....

 

Hey, I don't want to start a debate but have you considered dropping the resonator and putting in a K&N or Comptech filter. I only say this because I dropped the res and it sounds great and gave me some additional low end torque.
I was initailly going to go with the CIA but after doing some research and talking to a buddy who races cars I found that they really do the same thing except one looks better and one costs less.

Again, I'm not trying to start a debate because believe me I've seen whats been started in the past over this subject. Simply letting you know that this is an option.

 

I got the AEM and I've been happy with it...


Worth the $$$ IMHO.

1-5hp? Not. 8hp documented by dyno.

 

Interesting, any chance you could post that dyno!! I would love to see that!!
