Shhhh!

i dyno'd higher in stock form!

let me bask for a little longer!!

j/k lol.

I'm sold.. :)

Check out my dyno -- I picked up power through the rev range, although the magnitude varied over sucessive runs, those two clearly show some solid gains.

That's awesome work Jordo! +Rep

In stock form, I dynoed 280whp peak. I hope I can peak at 285whp with a set of these filters.

Just make sure you have the car at approximately the same operating conditions -- the more they diverge, the harder it wil be to interpret results...

They are a waste - i have two for sale..used for 1 day.

Just take a huge dump and leave your spare tire at home...you'll gain more relative power with the diminished weight than you will with stupid drop-ins.

so scientific. do you have dyno results.

A few whp can easily change due to intake temps. My first set of runs (with K&N installed) after driving down to the shop with no real cool down (less than 5 min), I made less power relative to both K&N after a 15 minute cool down or paper filter with a 15 minute cool down.

Allowing for equal cool down time, the K&N filters clearly made a bit more power than OEM, as was most evident comparing the first run for each post-cool down session.

It's entirely possible someone could dyno with a hotter car and see a loss that would incorrectly assumed t obe due to the K&N filters.

Failing that, I have to assume other transient factors like overoiling (can come from K&N overoiled!) or erratic fueltrim corrections --- the K&N's should simply flow better, so it would be weird to lose power even if you didn't gain.

drop ins
 

Just curious, is there a noticeable sound difference when using the K&N drop ins over the stock filters?

barely

:icon18: Lol, I second that!!

Actually, I came into this thread about that. I'm pretty shocked because they did make a difference. The motor doesn't sound so wheezy and strained anymore, it actually sounds lower pitched - more like the 350Z did. I swapped the OEM filters back, and the wheezy/high pitched tone came back (this is very evident to me in lower RPMs). I put the K&Ns back, and the tone changed again.

So if you don't like the sound of the motor and are looking for a quick change, definitely drop these in - they make just the right improvement in sound.

There's a teeny bit improvement in power, but it's mostly low-end and you have to be pretty sensitive to feel it.

Or remove passenger seat.. the thing weights like 40 pounds...

Or stop being fat...
