Still new to Mustangs, recommend a sufficient tune up. What brandplugs, gap, distributor cap, etc.
Thanks.

anything done to the mustang? what year?

if mostly stock, autolites #25 gapped at 32-35~ish
just get OEM or motorcraft dizzy cap and replacement rotor.

change your oil, fuel filter. check timing and make sure everything is good in the hood. any performance issues with it now?

.054 is stock gap.

Steeda or Ford racing 8mm and 9mm plugs are great bangs for the buck, and are very resistant to melting incase one slips into prolonged contact with the headers.

Stock motorcraft plugs are more than efficient for a stock/near stock car.

Stock distributer cap is just fine, but if you insist, MSD makes great products.

Stock coil pack is more than adequate, but again, you can go aftermarket if you insist, but it's not needed.

Gap is 0.054 as stated.

Don't forget to change the radiator fluid, tranny fluid, rear end fluid, and fuel filter.

Hehe... "radiator fluid"? I've never heard it called that before... lol.

Seriously though, I don't think it's necessary to change the antifreeze, tranny fluid, or rear-end fluid every time you change plugs, wires, or engine oil. Maybe once a year, maybe every x number of miles, but checking levels isn't a bad idea. Check your antifreeze levels in the radiator's sidecar every time you check your oil. Check your tranny and rear-end before and after any severely punishing use and/or once or twice a year. Obviously that changes a bit if you're racing a lot, but unless you're launching like a madman at every stoplight or on the track every Saturday, I wouldn't check my rear-end oil more than once in the spring to make sure the level's the same.

I sure wouldn't be bothered to check tranny and pumpkin oil more than every 10k-15k miles unless I have a real reason to. Then again, that's just me.

Oh, and be sure to use an antifreeze tester to make sure you're getting boiling and freezing protection though... and never run straight water in your radiator.

stock plugs gapped at .045" .054" is stock yes, but you'll see better performance out of smaller gaps and tighter spark 99/100 time son older cars

fuel filter, air filter, clean the iac and tb w/ brake fluid , cap/rotor, wires, make sure the tb blade opens all the way when you step on the gass fully, tps set to .990v , timing at 12* and keep using 87 (step it up if you need to...but if you go from 10*-12* and then go from 87 to 92 octane...you have done absolutely nothing other than use more expensive gas to negate the effect of the higher timing.

thats about it really.....if you have some problems...address them, i'd go over all your vac lines..the plastic ones get brittle and break

dudeboy

Yeah...
make sure you set that TPS to exactly .99v
