On Sunday I installed FM springs, changed diff oil over to royal purple, and changed my engine oil after a seafoam treatment. The New England rust was a PITA on the rear sway bar, but what killed me was that the K&N oil filter did not fit properly on the engine and my car pissed a couple quarts of oil all over the garage floor.
Anyone else have a similar experience with a K&N filter? I double-checked the part number on their website and its listed as compatible with the Miata, but its about an inch shorter than the oil filter I took off from the previous owner.
