SPARK PLUG TORQUE 20FTLBS or 11 FTLBS

LSXNV · 12-31-2005, 08:59 AM

I need to know if i torque down to 11 ftlbs (What Install University says) or 22 ftlbs (What my Haynes says). @ Install University it says hand tight, then maybe a quarter turn. When i torqued plug #1 down to 22 ftlbs it seemed alot tighter than 1/4 turn from handtight......

I would do 1/4 turn past hand tight. Thats the way I do it. Get it to tight and you could damage the threads in the aluminum block.

That's the way i've always done it also...make sure you put anti-sieze on the threads of the plugs.

You'd be hard pressed to get an accurate torque reading for the rear plugs on the passenger side anyway.

I've always done "snug + a little bit", and always use anti-seize

Fuck that....crank those things over as tight as you can.

Okay...So I am full of shit.
I get them tight, but don't force anything into place. Hand tighten, then get them so they feel a little past snug.

Don't forget to index them!!!! right guys?!?!?! Right???!?!?! DYNO PROVEN 1HP AT THE REAR WHEELS!!!!!!! come on guys, right?!?!?!?!

No but really, have you guys seen that? They say to point em all open end straight forward or something, rediculous

I've read that somewhere...more ricer propaganda. To anyone that does this...good luck doing it to the 8 plug.

Actually, this is not so 'ridiculous' as you say. The average street car may not see any difference doing this, but if you are trying to squeeze every ounce of power, it does make a small difference. It only makes sense to place the direction of the spark towards the main part of the combustion chamber. Personally I think it is better to use something like a Bosch +4 or something similar so that the spark is not directional at all.

bosch plugs are shit

**mcamp001** · 01-02-2006, 11:07 AM

why? I use them and they hold up well, and make good power. Why do they suck?

**oneBADDz** · 01-02-2006, 11:24 AM

I don't have anything against Bosch, but platinum I do. Platinum gets hot and stays hot and can contribute to detonation. 4 tips is just extra platinum to hold heat and contribute to the problem

I used to run the bosch platinums in my truck and my girls car...both started to get misses real bad after a few thousand miles...my girls car had a strong smell of raw gas. Put NGK's in there(the cheap ones) and the misses went away

I have NGK IX's in my ls1...runs great. Maybe it was just a fluke...never used them since so I wouldn't know.

EDIT:I have bosch o2's in my Z and haven't had any probs....so i'm not against bosch, but IMO their plugs are crap
