K&N 69 series typhoon intake + Nismo CBE. So far I like it. Saving right now for a Stillen SC.

Most popular intakes on the board seem to be:

#1 Stillen G3
#2 Injen
#3 K&N Typhoon
#4 Stillen G2

I personally got the Injens.

In all honestly I figure there is a minimal gain, some sound gain and aesthetically its pleasing to my eyes when I look in the engine bay :) I also wanted black.

Actually I had bought K&N drop ins first but this was when there was a backorder on post MAF tubes...saw a deal on used Injens...jumped on it.

I've always done Intakes on all the cars I've had.

The actual gain between different types/brands of CAI are very similar, I will suggest choosing a particular one depends on personal preference such as 1)brand, 2)ease of installation and maintenance, 3)price.

Other than those three factors, I think they all perform very similarly.

Performance wise, I tried K&N drop-in, the engine does pull smoother, not much but noticeable.

Installed the K&N Typhoon last month, it does pull even better than the drop-in and the breathing note sounds much better too.

I believe all the CAIs does the same and the difference between them are not much.

Choose according to your personal preference. :tiphat:

I choose the K&N Typhoon because 1) Well established brand 2) Good feedback from members (However, most of the good brand ie. Stillen, Injen, K&N... got positive feedback) 3) Easy to install and maintenance 4) Price vs Value.

Also, OP, there are TONS of threads in this forum discuss about CAI, from focusing on particular brand to step-by-step DIY guide.

Try to search around the forum, you will get even more info than starting a thread. :tiphat:

I would personally go for ppe lth over the FI. That is because PPE designed their lth to be equal lengths. Not sure if FI did the same but based on my research, FI did not. If you have evidence showing otherwise then I will stand corrected.

I really think that the PPE headers are underrated on here in the forums.

Don't forget to replace your old muffler bearings with new ones every 12,000 miles!

Anybody able to answer my question in bold blue above?

Thanks --- Bonzo

you get to choose which hp, bonzo. :tup:

i think i saw somewhere they were seeing about 3-4whp. with the post MAF you might get that consistently.

I found a dyno once - but I think it was for a G. One of those threads that linked to another...and another...and another. If I remember correctly, the hp delta was 7 (but don't hold me to that).

I've got the filters in and even those wake it up a bit. Feels like it comes up a bit faster. I'm going for round #3 on the Z1 tubes tonight. I haven't been able to get the damn things in yet after about 2 hrs. of trying. There's got to be some trick. Z1 did send me another set just in case mine are cut a bit long - very nice of them.

scott- when i did my HPS tubes i removed the front strut bar temporarily. also did a little bit of trimming on the tubes. hope this helps. :)

I ended up having to trim the passenger side about 1/8". Driver side fit fine in about 10 seconds.

The tubes + the K&N panels honestly made more of a difference than I thought they would. I can't tell as far as hp, but it definitely is punchier when you get on it...like it takes out some of the throttle delay. If you stomped on it stock, you felt it ramp up slowly. Now it's instant-more of an on / off switch. Kinda fun...

I don't know what a G3 feels like but I'm happy with this combo for under $200. I'm sure when my FI exhaust & cats get here it will feel even better.
