Reviews of Autolite parts For Business

I now have the new plugs which are autolite gapped at .027 as it is suggested by autolite and also in the Bentley book.

The truck is currently using Autolite XP5245 iridiums. Normally I would go with something from NGK but I figured if the Autolites were a decent price I would get them and they would probably last the life of the truck

If its just painted like some cheap plugs such as some autolites then yes its needed.

So here is my experience with gaps on this engine. The wife 09 Passat was misfiring so I decide to replace the plugs. I buy Autolite double platinums which were gapped huge. Turns out the 0.032 gap was not correct after all and it should have been 0.028. Big difference, this baby flies again (GIAC tune).

Long before I read all that bad stuff online about the Ford crowd having trouble with autolite gp's I installed them in my 86 Golf and have been on the same gp's now for at least five years. I'm sure they need to be checked but I can't say much bad about them tbh.

Don't use autolights. AC Delco for GMs & Motorcraft for Fords. Modern ignition systems are sensitive to plugs so I use whatever the OEM does (within reason)

Auto lights are trash, Bosch too. I can’t tell you how many times I get a misfire diag that the customer already put plugs in, only to find the garbage auto lights are the issue. A set of oem plugs always fixes it

I replaced the original ac Delco spark plugs (shown in picture, THEY LOOK BAD) and put with new auto light ones and changed the wire as well. However, after doing so, my truck has been running really rough, almost like it's cammed and misfiring, when its rolling in drive it like to have a little shake.

As long as it’s not auto lite plugs you should be good. I’ve seen those things hinder 3 separate rigs from running right. Once one cracked 100 miles after installing them, half way through a trip we had to sop at autozone and replace plugs

Don't even think the Autolite or Bosch last as long as Denso/NGK spark plugs.
