which plugs will be good for a 99 5.4?

1) autolite 103's
2)motorcraft 479's
3)E3s
4) denso's
5) NGK

i have just ordered accel c.o.p's from summit,are these coils any good?
thanks for any info you can give me

 

you wasted your money on the COPS, return 'em if you can and get the globals off of ebay (they are the company that makes 'em for motorcraft)


also run the motorcrafts intended for your truck

 

Run the motorcraft or autolites, ive had the autolites in for 26,000 miles and so far everything is good.

 

Stick with Motorcraft they are the safe bet. modulars are picky about plugs Denso and NGK have been known to work but stay away from Autolite Champion and bosch.. Get the global cops accels is junk and you can get a whole set on e-bay for nearly the price of 1 thats a no brainer. Send them accell back..

 

X2

Denso's (you'd need the IT-16's) are sweet, but pricey.

 

ok how many of you have actually used the accels? a performance shop told me they would work good in my truck...they build modular motors alot.i just want the reason you say accells are junk.thank you

 

The two or three that bought them and had failures were enough. Do an advanced search with Accel as the key word and you should find some info. We also avoid Granitelli's for the same reason. There has been mostly satisfaction from the Global users. Mine or on the way.

 

look at how many of us with boosted truck are running the stock cops??? how many lightnings / harley trucks / cobra's / mustang gt's??? that's proof enough that they are the best out there, sure the accels may work better for the first dyno pull (if they survive that long)


there is only one truck I know of that has any success with the accell cops and it's had about 6 miles in the last 6 years

 

Please tell me someone else is going to install these for you.

There's EIGHT of them , ya know. And, and .... Wires

 

ok...i guess i am calling summit..thanks a bunch guys.....i do plan on going s/c so better get the best stuff.

 

That's great. Your screen name is all ready


BTW - here's an install guide: http://www.densoiridium.com/installationguide.php

 

I plan on doing it myself, if I can ever figure out how to get the dang hood open!

 

It opens?

Don't fergit the di-electric grease. May wanna get some fresh boots & such while yer in there.

Good luck !

 

I thought I would take a chance on the boots, they were replaced about 30,000 ago when the plugs were done.

 

my screen name was for 99 f150 supercab but supercharger will work to in the future...lol
