[BadCarma]

Does anyone know if k&n makes an oem style filter that fits the 91 oem air box and part # of the filter K&N.or what the demensions of the oem filter are.I know k&n sells several universal fit filters and would like to test one on my factory intake
best regards david

Yes they do have a drop in filter, I have one in mine. Your intake will have a slight whistle at light throttle with the filter. I forgot the part number but it can be obtained at K&N's website.

Found it!part#33-2713. any h/p increase to speak of?and did your use the sealant they sell to bead around the edges.. well for a good seal that does not allow contaminants to slip around the filter?
thanks dave

I think you use the rubber gasket from the stock filter and reuse it on the KNN filter. Without the rubber gasket it wont seal tight on the OEM box.

Yes you re-use the factory rubber gasget. I do not know what power it gave me. My car dyno's at 237 H.P. and 188 Torque to the wheels. Assuming a 15% drivetrain loss that puts it around 279 to the crank. Or if you use 13% drivetrain loss that puts it around 273 at the crank. Either way, my engine is stock with the K&N filter so I say it works.

Any trouble getting the oem seal off the stock filter without tearing it.it looks pretty hard not soft.looks like you could trash it pretty easy

I personally had no trouble removing the seal. It is not glued on so it should be easy to take off.
