Spark Plugs

[Tommyg]

What's the best spark plug for an 87gn? I put in the recommended ac r44ts but Red Armstrong told me afterwards that I should have put in r43ts. What's the difference? Red does not return my calls.

really dont matter

43s are just a bit colder than the 44s. Meaning a lil less detonation with the the colder 43 but in reality a good tune, good gas and a reasonable boost setting, will give the same performance with either plug.
