Which Spark Plugs? Gaps?

MTU 50 · 05-25-2001, 04:41 PM

I want to change my spark plugs this week-end and I want to know what type I should use. I'm not looking for splitfires or platinums or anything like that. I will probably just get some Autolite's or NGK's, but I welcome any opinions.

Also, what should they be gapped at. Last time I changed them in my other Mustang I looked in my Chilton's manual and I think they recommended 0.52 - 0.55, but I'm not sure. What do you guys suggest?

Thanks

Jeff

I gave split fire plugs a try and now I run them in both my cars and truck. Put them in 200 hp merc and plugs dont foul out any more. Set gap at .054 in stang. 2.99 a plug + 1.00 mail in rebate at pep boys.
