I have read a ton of articles on here and it seems that there are both good and bad things about these short spark plugs(bosch platinum,accel shorties) who makes short spark plugs besides them and does anyone make a short plug that is not platinum. thanks guys

 

autolite i use them quite a good plug and resonably priced

 

I use Accel's header plugs and haven't had any problems.


I've been able to buy them at Advanced Auto and AutoZone.

 

Accel is the only one that makes a true shortie plug, denoted by a "S" after the part#.

 

I bought some accel header plugs and there the same size as the bosh platinums that I took off.

 

Another vote for the Accel header "U-groove" spark plugs.click here for pic

 

That's funny, every Autolite plug, standard & platinum, I looked at in two different auto parts stores were the same length as the standard AC Delco plugs (FR3LS) were. I ended up shortening a set of Accels myself, because they don't make a shortie plug for my application.

 

Yup. That's what I bought.

 

yep another vote for accel shorty u groove plugs.

 

these short plugs should solve the problem with installation right? I cannot get the plug socket onto a 2 plugs and I'm not happy. also which number plug would I need? my engine is an 86.

 

i hope a/c delco rapidfires work fine for me and my slp headers, i just spent like 30 bucks on them.

 

I gotta say, that must be a big benefit of the Hedman headers.....I run 'em with stock length standard old AC Delco plugs, and 90 degree boot Taylor wires and have NO problems with burning wires or changing the plugs....just the normal "header" annoyances, but that is a given.

What can help is cutting down a spark plug socket on the really tight ones......I did this just for the #7 plug. Every other one I can get to with standard stuff just fine.

Also, unscrewing the tip from the AC's and cutting a bit of off this can give you some more breathing room if you need it.....



I've tried all kinds of plugs, and I still like the Delco's.....I'm always tweaking the car anyway, so I usually replace 'em every 20k miles or so, it's only $10-12 a pop.......
