K&N drop ins are the best
 

How many people agree that the stock intake is the best? Well I have had two different types installed in my Z and the best one is the stock! With K&N drop ins. After market intakes on the 370z will make your car look pretty under the hood. But your car will be louder and slower. And not as quick as it was with stock intake, Just a real nice exhaust is fine. And save your money on the intake ripoff.

I would agree! the stock intake is pretty well made.

The gains on aftermarket intakes are pretty well documented in this very forum. They're not worth as much bang per buck (or per install complexity) as HFCs and other exhaust components, but they do work.

Have you tried Stillen's third gens?

Gen 3's are a good buy if you want to go that route, otherwise Drop ins with Post MAF tubes are ideal for anyone looking to save a few hundo.

The stock airboxes are very well made with optimum functionality. Drop in some higher flow filters and you'll be all set. Unless you want the bling of a CAI.

I've got the K&N drop ins and have just ordered the post MAF tubes (backorder).

Still I'd argue the Gen 3 intake delivers the highest gains given the dyno figures on the forum. If you take price into account I'd agree keeping the stock box is more HP/$. From what I understand the gains sort of ebb down progressively anyway once you get other things done on the car - e.g. HFC, CIA & intake.

:iagree:

No matter what the dyno says about your HP, The car is so much quicker in real life driving, with factory intake.

Right. :rolleyes:

AFE dry flow is better than K&N IMHO! no messy oils, just tap clean, or wash warm, let dry and pop in...hp/tq gains between the 2 are identical

AFE DRY FTW

After spending all that money, and pulling off bumper, to install a nice intake that actually works well , with no CEL, you really forget how fast your car use to be. Try this trick
and put back on your factory intake. You will sell that aftermarket intake right away.

Did you try this experiment yourself? Did you take before and after dyno measurements? The dyno and the real world do in fact align, and the dyno is a lot more trustworthy than gut feelings. There's more to a dyno than peak numbers, but any change in real-world driving would be reflected in the curves of the relative graphs.

Your statements seem counter-factual to a large body of existing evidence, which means you need to put up some pretty strong counter-evidence...

:confused:

all cars are different but if you dont notice a gain from a reputable and documented intake, then either your installation is wrong or your AF ratio got out of wack. The stock ECU is optimized for the factory parts, usually the introduction of an aftermarket part that changes AF will cause the car to run differently until the ECU somewhat adjust. If it doesnt then a tune is in order. But either way at the end of it all a good intake will have gains over stock
