Splitfire plugs

imported post

Ok, so when I bought my wing, I didn't know how old the plugs were, and figured that replacing them would be a good idea. So, I went down to my local autoparts store, and tried to get some NGK's. Well, they didn't stock the NGK's that the 1200 requires, so I put in an order for some splitfires. At $35 for the set of 4, I figured at very least I should be able to see a LITTLE bit of performance gains.



WRONG!



What I got was no power from idle to 2500k rpm, a loping idle that almost killed the engine, poor fuel efficiency, and since I thought "Hey, their new, it must be some other thing that broke" The little buggers cost me hours of time.

Yes, I got the right ones. Yes I gapped them correctly, and with a wire-style gapper.

In my humble opinion, don't stray from the NGK. (Heh, that rhymes!)
