Changed the plugs today. Noticed after I got home that I had bought autolite 24's instead of 25's. I swear I said 25's but the guy behind the counter also heard motorcraft when I said autolite. I know 24's are for boosted and nitrous engines and I am still N/A. Will the 24's effect performance at all? I kinda had to put them in. Being too lazy to want to drive back to the store (and not wanting to looks too stupid), also my old plugs were looking kinda nasty and I didn't know how old they were.
