Gents, I've run into a combination of issues. first my car was a 318 car and had a 340 swapped in it at some point prior to my ownership. it currently has a set of headers( that has steering parts going through them I'm guessing meaning they are cheap) that are too hole filled and rusty to salvage. my current set of headers does not allow the correct 340 oil filter to fit (k&n hp3001) the filter sticks out almost 1" too far. when i bought the car it had a progaurd pr 073 filter that was smaller but a constant cause of leak. now i am content with purchasing new headers but i am having issues finding any that describe fixing my clearance issue and don't want to invest 500+ dollars and have the same filter issue. any advise is greatly appreciated. thank you.
