Modshack, since you do alot of intakes and have had your bumber off to do your diy intake air duct thing, would doing your diy mod and drop ins be just about as benificial as an aftermarket cai?

A quick search of the forums for dyno results on the Gen 3 Intake should give you some independent results from forum members here, some of whom have spent a small fortune for the good of the boards documenting their installs and resulting performance gains.

On the K&N side, we've been using these filters with our intake systems since the beginning, and sold countless panel filters, and have had exactly ZERO problems related to MAFs, oil, etc. K&N has been hit with a myriad of claims, most of which can be attributed to 'internet rumor', so much so that they set up a division and research arm within the company to attempt to combat these (largely unsubstantiated) internet claims.

Also keep in mind that normal cleaning procedures for panel filters is 50,000 miles, and conical filters used with air intakes is 50,000-100,000. We recommend 50,000 miles between cleanings. Even if gains are minimal on a panel filter, the convenience of not purchasing paper filters more than offsets the cost of the K&N, and in actuality, probably the Gen 3 Intakes if you consider the life of the vehicle.

looks about right to me, a few hp gains here and there and I didnt see any loses and Im sure better throttle response too. So what I would expect from drop ins, which is what Im doing. Have them on order already.

They have an entire department set up to try and fail MAFs with oil, and have even gone so far as to have staff on hand to help with dealership issues if there is in fact a claim of the K&N's causing an issue..

When you say "drop ins" are you talking just K&N filters to replace the OEM Nissan filters in the stock cans?

Philipp, thanks for your efforts. Your dyno tests have made up my mind on the set up for my ordered Z. It's Stillen CBE and K&N drop in filters and nothing else. This combination should give me a 16-20 HP gain over stock with no warranty issues and that's the peace of mind I'm looking for!

So if I'm reading the charts correctly, we are looking at 4-5 hp gains in the peak range with the drop-ins?

As far as engine performance goes; it's my understanding that the stock air box set setup provides all the airflow that the engine can handle. :)

I can't see putting on a Stillen G3 intake without also buying at the same time a less restrictive exhaust in order and a required custom tune to get the full benefit of the intake. I can think of alot of better things to throw away $3000 on that will not depreciate the moment it goes on the car.:rolleyes:

You've read correctly. The gains were consistent throughout each 4 runs.
