Query: Love the Welded Lug

I've read a few studies based on the performance of K&N; oil filters, but I'm not an expert on engine performance or engine life, so I cannot proclaim that by using these oil filters you'll have a perfect engine. I can tell you that I put 135,000 miles a Dodge Cummins 2500; 1,500 miles on a Yamaha Grizzly ATV; 50,000 miles on a Ford F-150; and 115,000 miles on a Chevy Tahoe using these filters and have had no filter related problems.I change my own oil and started buying K&N; for the 1" welded nut and that reason alone. It makes filter changes immensely easier, for me. No more filter wrenches or pounding a screw driver through the filter to muscle it off.The extra money paid is worth it for me.
