Query: Doesn't fit application listed - waste of money.

If you have the 3.9 Lincoln V-8 DO NOT BUY stock number HP-2009. The screw-on hole is way too small and you'll be stuck screwing on your old filter and limping to your nearest parts store for one that fits. My first experience with K&N has been regrettable, never again. I should have stayed with the bulletproof Purolator filters.
