Good day Gents and Happy Halloween Eve. I will be racing SCCA Solo FS next year so I can not do a CAI, and have read here and there that it is not worth the cash, with 11k on my 07 I am betting it is air filter time.
Is the K and N worth it?
Is this the right one? K&N Drop In Replacement Air Filter 33-2649
Or should I just go back with a Fram or something?
Thanks in advance

I would run a Wix paper element (Part No. 42827). The problem with the K&N is that it only filters well when oiled and the oil can (and often does) foul the sensor wires in the MAF. You can run the K&N dry but it will not filter out contaminates. I really believe oiled filters, like K&N, have been rendered obsolete by the introduction of fuel injection and the associated need for sensors in the airstream.
Not sure when this filtration test was done, but it's an interesting read.

Thanks for your input guys. I think I will stick with a paper element and give the Wix a try. Pato- that article sealed the deal for me thanks for the link.
Glad to help. I run Napa Gold air filters after reading that.

I have run K&N drop in for a little over 100K miles. I oil it once a year or so and no problems thus far.

i have always ran k+n filters, i will check out other options next time

Two of my vehicles have K&N and two just the standard WIX. I don't think I would buy the K&N filters again. Easier to just throw on a new one rather then wash, oil, etc.
