Question about air filters
 

They say there's no such thing as a dumb question just answers anyway.
Why is there 2 air filters on the 370 and not the 350. Was it only for the HP
increase. Auto Zone wants 65.00 each for the K&N ones. I know by searching
on this forum it depends on who you ask but will there be any difference from the stock to the K&N ones. 120.00 can be spent else where on the car.

There's two because there are two plenums. One for each side of the engine (3 cylinders per side). You'd do much better changing to an intake system (either long or short tubes). Not sure you'll notice much difference with just changing out the filters and leaving the stock "accordian" hoses.

Use stock filters and replace when needed.

I just installed the k&n filters on mine. Not a huge gain, but still noticeable. The stock filters are about $15 each if you wanna go that route. PM Josh at Stillen for the K&N. I hate to say this but $120 for this car doesn't get you very far. Maybe an oil change and a light lunch. The Cobb tubes can replace the stock intake hose, but I'm not sure if you gain much. Makes it louder too. It kind of depend on how far you want to go.

The 07 & 08 350Zs has two air filters!

Bought mine at 370zsource. Paid about $91 shipped.

oh sorry didn't know about those two years i had an 05

When my time comes, only 800mi now, but I'll spring for the K&Ns. Like not having to replace, and just clean every 50K or so.

Try the K&Ns. You will feel the difference. And you will be happy you did.

Or just buy new ones and avoid the over oiling issues :)

I have used K&N air filters before and have never had any "oiling" issues!
