PUDdyPuller, I wonder if your install issues are due to your car being a 911 tub with a 930 engine in it (that's what you have, right?)? I didn't have to trim my filter base, didn't have to lower the engine, have had the filter on and off probably 6 times in the last two years (chasing running problems), and do not have a singe bend or ding in any of the pleats. It's either that, or maybe my superior pimp hand is the decisive factor?!?!
