K&N air filter?

My GC has the hemi and I'd like to put a k&n filter in it to increase sound and performance but wasn't sure if it makes a worthwhile difference with this engine. I was hoping to get some feedback before I spent the money.

Thanks,

ZZ

A filter alone in your stock intake will not make a difference in sound or performance.

I would highly consider it. I have one in my 2011 jeep grand Cherokee 3.6 V6 and not only does it make it louder but the performance and MPG both increase as well. I traveled cross country, 3,500 miles 3 months ago and at a constant 80 MPH I was getting 26 MPG.

Streetsideauto.com has the best prices. I think I picked mine up for about 230$ after taxes and shipping.

Its well documented that K&N filters flow more by filtering less. Their sales and marketing departments will not address this question directly. Google is your friend. The folks that buy their marketing hype will fanatically defend them with no conclusive evidence that the filter works as well as stock. Use at your own risk!

A good aftermarket CAI will use a substantially larger filter with more surface area to increase flow. Drop in filters MUST filter less to flow more since they are the same size. The laws of physics apply.

Re: K&N air filter?

One certain difference with a K&N is that more dirt gets in your cylinders. The Web is full of K&N "performance" discussions with the jist of it being that stock engine filters have more than sufficient air flow (CFM) figures while race motors that get rebuilt every season or sooner may benefit from a higher flowing air filter.

Added expense and maintenance needed to clean and oil the K&N doesn't seem worth it...I was a past user on tuned HiPro motors with data monitoring and never saw any real difference in HP/Torque...just "IMHO" as they say.

Get an exhaust. You will definitely be able to hear it then with borla or flow master.

Re: K&N air filter?

To help you, here is a linky to a scientific test OEM v K&N air filters.


K&N Air Filter Review - Debunking the Myths (and why OEM is better)


K&N are fine if you are on the track and rebuilding motors regularly. However, for everday users, they offer nothing....
