Autolite plug review for FI (better than NGK) - Page 2 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Hey Cisco thanks for the info man!

Great write up and info. Never heard anything to lead me to believe autolite was making a good plug. This is why I keep coming back !

That's how I should have asked the question.

IMHO, I've always had great performance from NGK's- but I don't think they make an equivalent to our stock plug.

Denso makes a performance plug that is- ITV20 5339. They recommend change intervals at 30K miles despite it being iridium, I guess cause it is so "high-perf".

I've been running them about 3mos. with good results, but haven't done any back to back testing. The stock ACDelco's are a solid plug.

We've used the autolites and NGK iridium here. I don't think you'll see much difference from one type to the other but the iridium plugs in general seem to run much better especially while the engine is cold. We've used Denso too and they seem also a little more crisp than a normal copper plug. We try to sell people the iridium plugs when we know they are not going to change the coppers out every 15-20k. The iridium should last a easy 30k miles.

I will say you might want to double check your tune. No matter how good the plug is it shouldn't be that dark on the base. That is a pretty good indication of too much fuel at idle and low load areas.

Here is a good spark plug write up we did a while back.

Interesting. Ill give those plugs a try next time. I do find it interesting that ipf suggested gap is .031 and RX is like .036-.038. I think mine are .037 I wonder if closing the gap would improve performance. However as far as I can tell, I am not having spark blow out.

Thanks for the info. Will check out those Autolites!!!

Hey we have the same name???? I was confused a bit there.

CiscoBee · 01-23-2013, 03:59 PM

What is the autolite part number for these plugs??

SC2150 · 01-23-2013, 04:10 PM

Blow out occurs when the amount of boost exceeds the ability of the spark to jump the gap between the electrode and the strap....so in most applications we use the NGK V-power as the size of the electrode is much larger, but gap needs to be reduced in relation to the amount of boost. At 18-20# we are down in the 25-28 range for gap. But under 10# not much gap reduction is needed.

Can't_C_Me · 01-23-2013, 07:34 PM

Ciscobee thought you had caught on in other threads we posted in lol. You get the thong jokes to I bet lmao.

Well seems like the perception we had about the so called cheap Autolite plugs are dead. Times have changed from back when out parents would show us how to work on a car. I am very impressed with my findings on them and will be using them again when the time comes. Cant beat a cheaper cost with better performance than the more expensive ones.

I was looking for a # is respect to output of boost made, Thanks SC
