I'm sure I've seen this here before, but I didn't find it. So I am posting it again. Sorry if it's been duplicated too many times.

These are the Ford F150 05-08 4.6 and 5.4 part numbers.

Brisk Silver Racing Spark Plug 3VR17YS - stock and light modified

Here is the TSB that details the plug removal process and how to "potentialy" keep away problems.

topic has been discussed many times but its always great to have it in the mix of the new posts so people are aware of it. Thanks for putting the TSB and the potential plug replacements in one area for us!

How much do those Brisk plugs run for the 04+ 5.4?

Brattonr

I've found them for about $16 each.

Buck

man.....$128 for plugs alone...thats hard to swallow

Brattonr

Not sure, but if I'm not mistaken the Ford (Motorcraft/Autolite?) plugs aren't any cheaper?

Where oh where has my FoMoCo gone?

crazykarl

well I have the 4.6 and understand they dont have the plug issue like the 5.4 does. I personally am going to go with E3 plugs. When I do I will let everyone in on how they do.

Buck

Ya I dont think the Motorcraft plugs are much cheaper if at all.....It still sucks they are so damn expensive!

4.6L 3V's have the same plug issue.

I think I am going to try the Brisk plugs in my truck. I am at 99813 and I just bought it like a month ago. So definately doing the preventive medicine!

Bought new coil over packs, probably going to by new injectors, and will buy plugs. Also buying new "u-joints" and greasing up everything. When I pulled the air filter on the truck it was the dirtiest filter I have EVER seen. It single-handedly caused a CEL. New filter fixed that CEL.

Buck

WOW having a filter so dirty that it throws a CEL is bad. U need to keep up on that stuff a bit more often in order for it to be actual preventative maintenance!

Are u attempting the plug change yourself?
