Default Gap the BR8EIX with a P-Mag?

Hello all,

I am just curious about whether or not people have been gapping their BR8EIX plugs when used with P-Mags to the .030-.035 that the manual states? I was told that these are pre-gapped however and donít require. Is this the case?

Also any argument over using BR8ES vice the EIXs?

Thank you!

Charles

I've tried both but went back to the ES. Lots cheaper and I just throw in a new set at condition inspection. On gapping the ES, I'm not real scientific about it but they've always passed my gap test. I'll be laughed at but I use a piece of .032 aluminum to check the gap. Probably most important thing for either plug is to check the resistance before installing the new ones.

I use BR9ES stock gap with a pumped up engine, otherwise the BR8ES.

Default Mind the gap

So is it no big deal to leave their stock gap?

Iíve bought maybe 60. I change em often. Have only found one with a gap that looked too small, maybe .020. Opened it up to .035. Rest appeared to be .035. No problems leaving them as bought. I use solid tip 3961

Even though they seem to be close out of the box I will always check it to make sure. I'd feel pretty silly (or worse) if I didn't and there was some Q/A lapse and it's way off, resulting in a problem.

Default .029 - .030

Pretty much all of my BR8EIXs are right around .029 - .030 .... these aren't the easiest to gap. You guys think it's fine to leave them here?

Thanks

I'm not an expert on ignitions so I'll leave it to others to say whether .029 is okay. However I don't find them hard to gap, I use a piece of .032 AL to check it and some smooth jaw needle nose pliers to tweak the gap.
