• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

do your mods in this order first let it breathe with headers and a cone filter then get a tune and 180 deg t stat those are basic mods then after that you can consider smaller pully but make sure when you drop pully size to get a in car tune for best results and reliability

103's are way too damn cold for your car



agreed. they're beyond a fail plug



I wouldn't recommend the OBX headers to even my worst enemy. They are that bad. If you want to talk about saving money then get the SD Headers...they are the exact same as the SSAC's which are knock off headers of SLP's.

Ive driven my car with these plugs for over ten thousand miles. Never a misfire, never a sputter, not one problem. With your expert opinion, can you tell me what you think will happen to the car with plugs that are "too damn cold for my car" id like to know. Ive talked to zzp about this and the only consequence they could come up with was they wont last as long. But hey they are no experts, only the largest vendor of w-body parts in the world.
 
ZZP has been proven time and time again to be wrong with many things. They are not a good plug for that application. And no, not lasting as long isn't the only thing...you'll get worse performance (probably not noticeable but it will be there), worse MPG's, and the plugs will not last as long as they said on your setup. Autolite 103's are for setup's sitting in the sub 3.0" pulley range...big cam/heads cars or cars with big injectors/tiny pulleys and or a full size IC. To tell you how much ZZP knows...they didn't even know programming mode meant when they messed up my PCM 5 times. Not to mention the countless complaints on customer service lately along with getting LAUGHED off of CobaltSS.net for their lack of knowledge on the LSJ platform. Plus, since I know nothing...I shouldn't know that you also want the hottest spark as you can get away with...without knocking. AL104's would be ideal for your car...but I don't really care in the end...because it isn't my car. Will your car suffer, probably not. Could it run BETTER than it does now? Yes. But take ZZP's word for it since our's isn't up to your standards...and I was talking about the Bosch plugs being a "FAILPLUG", not the AL103's...I run 103's in my car...but it is a big cam/ported heads/injectors/LS1 TB/tiny pulley/meth injected setup

Ok so performance will suffer, but not noticeably, and the mpg's will go down. well i got the same mpg's after i changed my plugs to 103's.. So this must also be not noticeable. Therefore we come to the conclusion that BOTH those two things, being not noticeable, obviously dont affect anything drastically. which leaves us just with what i said, that the only thing suffering is the life of the plug. So with you saying WAY to damn cold. I think you are off by a little.

And to the Cobaltss.net complaint, i know, yet their knowledge of the LSJ platform has nothing to do with what spark plugs will work in an L32. I am also a member on cobaltss.net, i have a redline.
 
people like bluegtp need to get over themselves. Be open minded and not arrogant. I never asked anyone if they thought my plugs were too cold so in other words i dont give a ****. nice try oh wise one
