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

My small contribution to the community! You will enjoy your new car. Mine is getting better every day

and has less than 4000km...

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

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

My experience with the drop-in K&N is that I didn't notice any power increase--no loss, either, BTW!--but I'm now getting two weeks out of a tankful, versus 11-12 days I was getting prior to installing it. So, even if you don't get a whp increase with it, the gas savings are well worth it, dudes! Greetings from sunny/rainy Puerto Rico!

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.

LOL...OK.

No, there are no performance gains from a G3 intake...none at all...lol

The Z depreciated more than that when you drove it off the lot...

4-5 hp, or 3-5% gains? Please clarify. The literature that came with my K&N air filter used percentages to measure the gains. Allegedly, my '04.5 Touring Coupe gained 3%, which=8.61hp. Any experts in the house??

Nice job. The KNs do what they claim, and is what are expected of them. The graph shows a consistant air flow with KNs vs. stock.

As for over-oiled production KN filters, it is mythical horse ****. Certainly, there may have been a few that have affected MAF sensors, however, the majority produced are without problem. The reported problems of soakage is commonly associated with persons re-oiling their KNs.

I have used KN filters for almost two decades. In fact, it is the first mod on my new cars. No problems.

I've used K&N filters for years on high-performance motorcycles and have nothing but good things to say.
