370Z K&N Dual Air Filter

6spd · 05-21-2010, 11:55 AM

I looked at a filtration test/comparison between like 5 or 6 companies' air filters, K&N included, conducted on an R34, and while all averaged 4-5 hp, the levels of filtration varied greatly with HKS being the worst and K&N being second best. K&N only lost to a paper filter though, but HKS was rated as very poor for filtration. This was the usual drop in filter too, made of the same material. This made my decision a lot easier.

no problem, if you do get the K&N's, youll enjoy them, i know i do!

Its good practice not to open up a brand new filter and install immediately. You should let it sit out overnight (at least one night) to dry out a bit. If k&n heavily oils their filters then maybe let it sit out for 6 months?? LOL.

I've got a set of K&N drop in filters, but I don't want to waste my stock filters just yet. I'm at 7000 miles, when is a good time to replace the stock filters with the K&N filters?

I kept mine. I put them back in whenever I go to Nissan for any service. I just don't want to give them any excuses.

After you read this.

I just checked the Maintenance Guide and our engine air filters are good for 30,000 miles. Nice. I guess I will replace it now and just keep the stock filters for any future use.

Just read this entire thread and ordered mine. Lots of great information here.

I had a $75 gift certificate to Amazon.com and couldn't think of a better way to spend it. Cost me a total of $13.88.

Looking forward to getting them on the car.

Keep the stock filters for when you clean the K&N's. When you clean the K&N's, you spray cleaner all over them and then flush them out with water. Then you have to let them dry before re-oiling them. While you're waiting for them to dry out, put the stock filters back in so your car isn't grounded while waiting.

Installed these yesterday. Car feels more responsive and sounds deeper/better. Love them.

I have used K&N Filters for over 20 years. I have yet to have a problem with the oiling issue. I make sure I follow the directions when reoiling the filters. In every car I've installed the drop in filter I've notice a slight improvement. In all cars I notice gas mileage improvement as well. Well worth the $50 or so per filter.

Add a free flowing exhaust and you she'll give you a little more power.

I have custom exhaust with 12" resonators and K&N drop in filters. Sounds wicked. Easy return to factory stock if I ever need to. Four bolts for the exhaust and a couple clips for the filters.

Cheap fun mods is what I want for this car. Now, my other cars are money pits. Money is no object in getting more power for those cars. It's like a huge hole in my pocket. Where did that money go? Oh... :-0 that's right... I forgot about that part.

My wife says it's always like Christmas around our house for me. I'm always getting presents delivered. He, he, he.... ;-)
