Spark plugs

[matt texass]

Ok some jackoff that sold me my new ht0 plugs at oreillys told me that if i dont gap these plugs im gonna tap a piston ( how far exactly is the pluf from the piston)..... Im 99.99999% sure there is no truth to this but i just want to be extra careful with my car.

sorry about this dumb question,
matt

Rest assured that there is no chance of that happening.

Having said that, you do need to gap them for your application. They come stock at .045.

How much were they at O'Rileys?

i didn't gap mine at all and had no issues. im running a .032 gap now with the KB

Go back and smack him over the head, I've NEVER seen a plug that was that close to the top of a piston. The plug would have to extend below the deck surface of the head with the stock gap (not going to happen).

The guy was loony and get the plug gapping tool from Josh or Kevin at PMP, great part for a good price.

Wow, that guy at O'Rileys better call Ford and let them know....

If your N/A, I would keep them at .045. If you have s/c or turbo, gap accordingly. Most gap between .032 to .035 depending on how much boost you are running.

 

[matt texass]

no boost just giggle gas

Oh, cool. When I ran the 100 shot--I still stuck with the stock gap and had no problems at all. On the 125 I still used the stock gap, just ran 100 octance Unocal so I could run more timing. When I went to the 150 shot, I gapped them .035 and ran 104 octane. I resisted gaping them down because my car is a daily driver, and when I ran the HT0 with .035 gap N/A, I noticed a drop in performance.

What size shot are you running??

 

[matt texass]

100 but i have a tune also did you run a tune... the only reason i have a tune for it is i get them for free basically

 

[psfracer]

Yep, I ran a tune that kept the A/F at 11.5-11.8 with the N20 engaged. With the 100 shot the timing was still stock, I didn't start backing off the timing until the 125.

To get my A/F where I wanted it, I had to run a fuel jet 3/1000ths larger then what the chart called for. (Example .038--I ran a .041)
