Its a small DIY upgrade. Doesn't cost that much, except you need to replace the filter every 10K miles.

After trying several different elements I was disappointed. I knew they would not give me any gains, but expected better revving or something.

Well, the Nismo S-tune Sport Air Element (dry type) made a difference. My butt dyno is very skeptical of any mod. I can say that the car felt stronger and was quieter than with the K&N filter. I'm guessing the change in sound has to do with wet type or cotton vs paper, but the lower engine growl and whistle of the K&N is gone.

The price. How can I justify it? Well, I spend that much in gas a week here in SJ, CA. So for something that last a year, means the gf will get two less dinners. LOL

 

I would guess that the reduced sound level also means less air flow ...MHO

 

Today I really got to "play" with the new NISMO air element. I have to say the car is quieter only below 2900RPM. The engine note is completely different from the K&N. No whistle or growl. Its more a hollow sound. I'm very sure this filter is less restrictive than the K&N, but that probably contributes to its short life.

Does anyone know about the details of the NISMO sport air element wet type?

Do I have to order from japanparts.com and be the first?

I want to know if it can be cleaned. Japan parts claims NISMO says its 30% better flow.

 

the "NISMO WET TYPE" filter is a regular wet type NISSAN Filter element that was originally equiped with the Z / G35...

the Dry Type element is cool but wicked expensive... we have them priced alot lower then we should on our web site (close to cost)

 

Jason -- so the wet type is not oiled like K&N. I did not know the the orginal filter was wet type. Can you explain how it is wet?

 

its red saturated with an oil...

atleast the ones in the G35 coupe are for sure... or were... I havent pulled one for a while... and I usually never pull them out of stock air boxes... Ill pop one open from a new Z on the lot and see what is coming with them now...
