Plug Gapping Question

[FordF-SuperDuty]

When I install my plugs I'm also going to be using all the parts from the 6 Liter tuneup (MSD Cap and Rotor, MSD Blaster Coil, Motorcraft Copper plugs, and Ford Racing plug wires) but I'm not going to bump my timing, the tuneup talks about increase the plug gap from stock (.042 to .055) but since I'm not going to bump my timing should I still bump my plug gap?

when i did that tune up i didnt bump my timingm but i still set the gaps to.055 it runs like a gem

 

[flareside_thunder]

I was gonna say, the timing won't have anything to do with the plug gaps....It's all in the coil and upgraded parts that go along with a 6L tuneup....gap them badboys...

 

[FordF-SuperDuty]

Stock is .042.

 

[crzybil87]

if you did the tune up itd be a waste not to gap them plugs, so gap em

 

[LEB Ben]

Gap em...but I'd still check in a couple hundred miles how they're burning.

Another question, doe it matter what way I put the plug wires on the cap?

 

[FordF-SuperDuty]

Did oil, air filter, Coil, and coil. Still need to do cap and rotor, plug wires, plugs, and clean IAC. Seemed to run a bit better.

what do you mean? like the order? YES!! thats the firing order...

 

[flareside_thunder]

Sweet, now finish the job!

 

[crzybil87]

What do you mean which way to put them on cap? which end of the plug wire? usually the 90* end goes on the cap

No, I mean does it matter where each plug wire goes on the cap.

yes it matters. You have to follow your firing order

yes it matters. You have to follow your firing order

It isn't labeled on the cap, how will i know which is which?

when you changing the plugs and wires. do them 1 at a time!!! ONE!!

Lay out all the new wires shortest to longest.

when changing the plugs and wires pull the single plug wire off and match it up with the closest length new one..

this is so you dont mess the firing order up..

 

[73F100Shortbed]

#1 is labeled. Then you have to follow the firing order for your engine.

EDIT: Like Chris said it is best to do them one at a time so you don't mess it up. I've done it by removing all at once and one at a time, depending on what I was doing. But it is probably best for you to do them one at a time.

 

[crzybil87]

usually every cap ive come across has a mark under the cap for the #1 plug then you can go from there and do one at a time to avoid messing up or confusion

 

[flareside_thunder]

In case you do mess it up.... it should be counterclockwise 1 5 4 2 6 3 7 8

 

[FordF-SuperDuty]

Mine, which is a MSD is not labeled.

 

[crzybil87]

really?, mine was a a little #1 next to the point thats susposed to be #1
