MG MGA - Spark Plugs

Are all spark plugs created equal , or with modern technology has anybody got any views of a particular make and grade that suits the 1588cc engine best.

A lot of folks here have recommended NGK BP6ES in the past, and therefor that is what I run. They work great, but I am sure others would too.

There is a thread about Iridium Spark Plugs further down this BBS. You may find some of the postings interesting.

B6ES is what NGK recommend and that's what I use. BP6ES are OK but you may experience pinking and running-on because of the extended nose.

I have had the best luck with old fashion Champion N5C. I have had good luck finding them at farm supply stores for some reason.
Keith Lowman

I recently had problems with Champion plugs arcing in very colorful and misfiring ways. I'd avoid them.

Barney Gaylord posted some interesting results of a 10 year, 73,000 mile test on a set of Halo (ring cathode) spark plugs.

Yeah, but I would never buy the things. Too expensive. Other then that one test, I have been using Autolite 63 plugs for about 20 years. They're cheap, and the work. What more can you ask? Resistor type Champion plugs are notorious for about 10% failures right out of the box due to too high resistance (like open circuit).

I'm using NGK BP6ES with no problems. And I run about 9.8 to 1 compression ratio. No pinking. It's my understanding that NGK plugs have a wider, more forgiving heat range.

When I used the NGK Part finder online it comes up with BR6ES. Has anyone got experience with them?

Kenneth, BR6ES are OK too, but they are resistor plugs and are suited for radio suppression. I have been using BP6ES for the last six or seven years in my MGA 1500, and have never yet experienced any problems with them.
