Except for gimmick plugs, a plug is a plug. I run non-platinum plugs on my cars. I have used Champion's, AC's and others on cars and have never had a bad one.

Wires are wires, on a stock car.

Do not buy a high output coil, no air foil, no fancy distributor and do not buy bigger Throttle bodies or injectors, they are all a waste on a stock engine.
I run Summitracing 8.5's on mine, I like the extra insulation because I have headers and I had Bosch on before, with no problems.

Now when you start modding, forget all this!!

BTW: the word is which, not witch(this is not halloween).

 

Why in the world don't you identify your Corvette so you can get some help!!!!!!!! Every year C4 did not use the same exact spark plug!!!!!!!!!!!

 

From his profile, it looks like he has an 87. But, yes, it really helps to identify the car year.

I have a set of AC Delco Rapidfire #5's waiting to go into my 87.

For plug wires, a stock set will work well if the engine is stock or even has mild mods. MSD, Taylor, AC Delco, and ACCEL all have good sets that are designed for the factory wire routing. Plug #6 gets a 135 degree bend at the plug end. The generic sets will have extra wire lengths that will look messy unless you go with custom looms.

I would stay away from the chain parts store wire sets.

For a distributor cap, get an ACCEL 8131 cap and rotor kit. This has brass terminals and will do a better job of passing current over a longer period of time. The 87 uses a screw-down cap not the clamp-on type. Both Summit and Jeg's have bad info for a cap when you go thru their selections.

Timing is 6 degrees advance but you need to follow the proper procedure for setting timing. Idle speed is controlled by the ECM. There is a specific procedure for setting initial RPM but you do need to understand how that process works and how important the TPS voltage is.

Find a factory service manual (FSM) and it will have the proper procedures.

 

The few different custom wire sets I've tried, including AC Delco, were way to damn long on my 89. Example, I had an extra 5" on #1 I had to figure out where to put it.

But the boots on the AC Delco are longer and make it very hard to click onto the spark plugs. I ended up returning them as it was a waste of time trying to get them to click.

I got a universal set of Taylor Spiro Pro. That is the same set the PO put on. That way I can cut them to fit.

The only thing is they are all 90* boots. And you do need that straight boot for #6. But mine has ran several years with a 90* boot on #6. The only thing is the boot will be pressed up against the oil filler tube. Though, you can order a single 135* boot wire from Taylor.
