Well, this is embarrassing...

What size spark plug socket do I need? I want to see if my spark plugs are fouled up from when I originally had my headers installed and a massive exhaust leak

 

Its the smaller of the two standard sizes, 5/8 I think

 

5/8 is correct.

 

This may seem dumb but It actually is a good idea to buy the one on ebay that is cut! I have cut my own and shortened the length of it and combined with a 3/4" ratcheting wrench, It works a hundred times better and is alot easier to use!!!
