Selling Porsche Boxster 986 lower spark plug tube seals. These are genuine Porsche OEM parts, and are brand new. Part # is 999 707 343 40
This is a great deal for those that have oil leaking past the spark plug tubes and onto the spark plugs. Replacing these preventatively is also a great idea if you are down there doing a spark plug replacement, etc.
I have two sets for sale, each set has 6 O-rings, one for each spark plug tube. Selling for $20 each or $30 for both. Price includes shipping!
