Spark plug removal

**98ss** · 06-15-2009, 06:34 PM

I just got some tr55 for my pretty much stock ls1 camaro. I have headers, y pipe exhaust, air lid, and i think a small cam. I would like to know a good gap and how the h@$% do i remove the passenger side rear plug wire and plug..

.052" for the gap.

Remove coilpack to get to that #8 (passenger rear).
Also, a 1.75" long extension is a life saver for me on that plug.

I have mine gapped at .035 -runs great. A local mechanic who specializes in LS1's reccomended it. All I have is a lid,NGK tr55 plugs,K@N, and MSD 8.5mm wires.

After you have changed plugs once, 45-60 minutes is ample amount of time to change them.

U might be right!!!

I am sure U are but when I make a joke on how hard they are to get to... and someone that always harasses me throws out 45 mins it hard to believe! I would still like to time him at 45 mins... I start my timer when the tool box opens!

So Peace
Gentlemen!

...back to the plugs, for many headers, the passenger rear plug is easy to get to from underneath.

Stock gap is .060, with your mods I would start there.

**JoshieDoom** · 06-16-2009, 01:11 AM

I gapped mine at .055.

It really does take 30-40 minutes once you have no emissions.... 15 to do the first 7. The rest of the time is spent on number 8.

GM changed their mind (from what I was told) and no longer recomends a .060 gap.

I gap mine at .55 and am pretty sure that's what my sticker says too.

A new spark plug has been released for use in the above vehicles. The new spark plug has an Iridium tip instead of the current Platinum tip. Due to the different tip design, the gap of the spark plug has also changed. The new spark plug, P/N 12571164 with AC Delco P/N 41-985, is gapped to 1.01mm (0.040 inches) when the spark plug is made. The spark plug gap is set during manufacturing and should not be changed or damage to the spark plug may result. Any new spark plug found to not be properly gapped should not be used.

Document ID# 1396703

So if you're not running the iridium tip plug noted, you should be fine with stock gap.

I drove mine up on ramps for my plug change. I got the number 8 plug and wire from underneath, it was easy that way.

Don't even bother messing with the coil packs. I spent half an hour messing with them, only to not be able to get at the last bolt. Turns out I had plenty of room with them in place, I didn't need to touch them anyway.

Oh, and a .75 extension comes in handy.

I think the lesson to be learned here is there is more than one way to skin a cat. I think most do it a little differently it sounds like. I take the coil packs off as I left the back bolt out of the bracket when I switched heads so removing the coil packs literally takes a minute or two. I also get that plug from the top with an extension and swivel. I can change my plugs in 45 minutes or less depending on if I have to take a whiz in the middle of it or not.
