claimed 8.17 HP increase

 

I would be willing to bet that there is power loss. One last thing to upgrade then

 

Wow... $428 from the K&N online store. Wonder if its cheaper anywhere else. I'd be happy with drop-ins for the stock box.

 

K&N has been pretty reliable to date on their claims, no?

 

dyno chart looks good

 

i would be willing to bet your statement is totally ambiguous. where would there be power losses? are you saying that this setup would drop your torque readings 100% through the power band? i highly doubt it.

now, will there be losses from 1800 - 2500 rpm? probably. but above ~2500 rpm will show gains. if you're keeping your car on the road when you only drive the speed limit everywhere, it's definitely something to not worry about.

as for me, when my car is tuned and i'm racing - these intakes will definitely help the car.


also, that dyno chart doesn't look biased at all. it's not a "stock 350z producing 290whp with a 8hp increase type of B.S.".

 

Any installed pics? I couldnt find any.

 

KManZ is probably right. The other open concept intakes have shown no power increase and some have shown a power loss, because of heat soaking from the engine.

I may be wrong, but from what I've read on this forum about the other intakes for the 07's they don't really do anything at all.

 

well not very many people have bought them and dynoed their cars. i've searched before, and i just tried again. there was a guy who bought the injen (i think) setup, but he used a dyno that corrected for engine horsepower.

but you know, pretty much it goes down to who you like, when it comes to cars. k&n has always been a competitor and has a history of quality products.

 

Id be willing to try them, but not for 400+. Thats just too much for some intakes.

 

ive gone through 3 intakes on my 06 and k&n is the only one I actually felt a difference and the dyno proved it too

 

maybe I should sell my popchargers and try these... so far looks like AEM is makin about 1whp more than popchargers.... I might have to give these a try...

 

Anyone try these out yet?

 

Dosent look like it. Injen is about to release some that actually relocate the filters out of the hot engine bay.

 

All the mods for the VQ35HR = year 2003 all over again

 

^^
I was getting nostalgic thoughts also.

 

just like every other intake design that has hit the shelves for the 350z, it will lose power or be LESS efficient than the stock air boxes. That's not going to change because the stock air boxes are still up to par.

 

I remember when the only mod for the 350Z was a grounding kit. Man those things flew off the shelves like hot cakes.

 

wires are incredibly awesome

 

Meh if there isnt any airbox that actally shields the intakes from heat, then its not worth it to me. Id like to see pictures of it installed.
