Stock would be 25 so i wouldn't get too tied up in that aspect of it a power steering pump with a remote reservoir could be an easy solution fixing the contact could also be handled by just mounting the air filter slightly away from the pump i cant say for sure without seeing your exact setup i wonder if you used the stock 40 location for the pump or not using the 25 brackets might either solve or cause the contact problem i wouldnt go with a kn type of filter system one using a stock filter is better you know for filtration engine will have far less grit and grime way better for engine longevity
Boy wouldnt using punctuation make this easier to read i think it would be great if everyone knew how to use it dont you agree
