Edited: 1/13/2009 7:00:40 PM by corey0814 someone advised me to use the iridium's for my corolla (daily) because they'll up your mpg like crazy & i thought they were full of it, but auto zone owed me $25 in store credit, so i thought "what the hell?"  i used them & honest to god, i got 5-6 mpg difference.  they're about $8 ea, but eventually they'll pay for themselves.  i put a set in all of my vehicles!  motorcraft does make the iridum for fords too...

use the factory motorcraft plugs, everything as far as aftermarket plugs and wires are basically junk when it comes to our trucks.

Just because companies make parts for other companies, that doesn't mean they are made to the same specifications.   I will only speak about my experiences at the shop I run.   I have seen many problems with autolite plugs that didn't last long, many more than motorcraft

Edited: 1/14/2009 1:17:06 PM by Kmanuel I had a customer show me an email from Honeywell that said they make both autolite and motorcraft plugs.It says that both are made to quality specifications, it didn't say the "same quality specifications" It also said that Motorcraft plugs are built to ford specifications, the email didn't say autolite were built to ford specifications.While many people will be satisfied with autolite plugs, is it really worth a couple dollars a plug to find out? "As a division of the Honeywell Corporation, Autolite is the manufacturer responsible for the production of all Motorcraft spark plugs in North America for the Ford Motor Company. Both Autolite and Ford/Motorcraft spark plugs are built to quality standards using quality components. Autolite manufacture's the Motorcraft plugs based on the specific design requirements of the Ford Motor Company. Autolite and Motorcraft spark plugs are manufactured side-by-side at our facility in Northern Ohio."

I agree 100% a good analogy would be ppg paint makes omni and if your a painter you know they arent even almost comparable.   you can do a lot of different things under one roof!  my room mate makes better dinner than me and we both use the same kitchen! lol.   anyway thank you guys for the responses.   ------------------------------------------- Originally posted by Kmanuel Edited: 1/14/2009 1:17:06 PM by Kmanuel I had a customer show me an email from Honeywell that said they make both autolite and motorcraft plugs.

I love my f-150 except the fact. I keep hearing about these horror stories of spark plugs coming outta the block...   Anyone recommend any injectors? I have a slight miss at around 35-40mph. Just changed all my coil packs and spark plugs with motor craft. Runs alot better but still get a slight miss when its cold as balls outside.   Mikey what rims are those? I been looking for some 20s or 22s. Truck looks killer.
