Daytona tune up

Hello, I was wondering what spark plugs to buy for a 89 Daytona, 2.5 turbo
? I've seen so many different ones and some are really expensive. Any ones
to stay away from ? Thanks

 

By far the best choice is to go with the OEM plug, which is made by
Champion. Stay away from any 'splitfire', NGK, Bosch, etc., you might run
across. I would also avoid platinum plugs for this vehicle in particular,
since it wasn't spec'd for it at time of manufacture.

Thanks alot Geoff. I appreciate it.

 

Non-gimmick. My preference is for Autolites rather than Champions, but
some have had the opposite experience. NGKs are also of fine quality. What
you want to avoid is the very expensive "something for nothing" spark
plugs. There's no advantage to a Platinum spark plug in this engine,
there's no need for multiple side electrodes (e.g. Bosch Platinum Plus 2
or Plus 4), and "Splitfire" is a load of BS.

That said, there are a lot of different non-gimmick plugs that are
available. My "pet" plug for this engine is the Autolite 925, which has a
doubly-long electrode set. This moves the spark closer to the center of
the combustion chamber and tends to improve ignition a little, especially
during cold-start/cold-run conditions. The Champion equivalent is RN13LYC.
