I was wondering if there any better plugs than what the owners manual
specifies? Something like double tipped platium plugs?
Got a '90 Cougar 3.8 V6 and had the engine re-built last May at Engine
Techs in Spring Valley near San Diego. Bless their hearths they did a
great job. The owner Umberto is a great guy. The car is running great
like when 1st got it.
Thanks in advance for any info.
