has anyone ever found a good replacement for this junk cap? tired of dealing with the aluminum post crab cab and the misfires. has anyone found one that has brass posts and/or a standard style cap that will fit to do away with the crossover problems with this cap?

A billion yrs ago when i started putting plugs in customers trucks/boats with .035” gaps vs crazy large OE gaps of .050”-.060” i barely ran into cap issues that plagued rest of country.

I get ones from AUTOZONE that are brass...

what brand? all the ones I seem to find are aluminum.

Crusader marine stuff is usually much cheaper than volvo and merc stuff. Last vortec crab cap got from there was brass.

.035 gap plugs and send it

not going to send it as it is my dually which is why I hate these aluminum ones. it sucks to climb back there to change it. after several conversations on here I have been gaping everything to .035 but I dont remember when I last put plugs in my truck or what I set them to. one of the hazards of not driving it very often. I probably dont put more than 6 or 7 thousand on it in a year.

I wish I could remember...I have the box top in my glove box in the boat...that is 300 miles away...

My bad...I just looked it up on my spreadsheet I keep...it's a Sierra 18-5354.

That’s not the HVS crab style cap.
