Re: Spark plugs for 91 5.0
Any specific brand? And was gonna do the MSD STREET FIRE coil, wires and cap and rotor. Should I change ICM to something better too? If so any suggestions.

Nothing to be gained unless your current parts are failing. ACDelco still offers the R43TS - R45TS the car came with, and short a longer service life, you're not gaining much by using a more expensive plug.
Things like the coil, module, etc the stock parts are likely as good or better than the latest out of Taiwan. Don't fix what ain't broke.

Well it's time 4 a tune up anyways. She's got 15,000 on old plugs n wires. And she is idling a lil rough. It's like a lil surge not bad just a couple hundred to RPMs but it still bothers me

How do you know that plugs are the problem? The default thing everyone does it change "plugs and wires" when they are just fine lol, plenty of money for the parts store

I use the basic delco plugs. Last I saw, MSD Streetfire was made in China. I used a Hypertech cap and rotor. Said Made in USA. Hope they still are.

I have a set of AC Delco plugs BNIB if your interested.
They are the R45TS
I can send pics to your phone if your interested.
I put the ZZ3 heads on and didn't realize they had different plugs until after it was to late to return the plugs.

Plugs and wires are generally good for a lot more than 15K miles. Some for over 10years and 100k miles (I don't recommend this) if you keep all other systems up so you are not burning oil or rich/lean.

I had split fires once. Didnt notice anything other then they were much more expensive. Same with the triple edge windshield wiper blades. As I've grown more mature, I realize they're just scams.

I took out splitfires in my car. I had no idea they were in there. And tight also - I thought I was going to break off #8.

There were reports back in the day where one of the 2 tips on the end of the plugs would break off and cause engine damage. They may have been sued for that also.
