Spark plugs and wires for a Chev 8.1

I put 2 air scoops on mine it keeps the wires so they last a whole lot longer.
I got the kit at a work horse dealer

Yes they were the cheapest that would work. Never be afraid to improve on what was originally installed. Times change and quality of products improve. The oil available now is not the oil that was available 30 years ago. We know have better insulation for spark plug wires. Better tiers. Why not look for the better quality products than the ones that are marginally suited for the job.

I replaced mine last year with the same ones that were on it.

I never use after market products on ignition parts or oil filters.

I recommend that you go to IRV2.com, then the Workhorse owners forum.. then search or ask the question.. Their is nothing like asking a bunch of Workhorse owners for opinions.

Yes, add that air dam and keep the wires cooler. We tried expensive Taylor ceramics and burned them out in less than 600 miles before adding this kit.

Changed plugs/wires last year on mine to the Taylor extreme with the heat boots and still burned #5 & #7 wires. These things are way too expensive to keep doing that and I was going back to OEM, then I saw/heard about these ceramic booted wires from Summit Racing. Can't tell you much yet as just put them on last week. But they looked well built and if that ceramic can really withstand the adverstised 2000 degree heat then that works for me.

You should be looking into the Workhorse cooling kit which was designed to cool the rear spark plugs on those coaches where the manufacturer did not provide enough frontal ventilation. This is the Engine Ventilation Cooling Kit Part #W8005026. It sells for about $200 but it includes new wires and shields. Cooling Kit

I don't always believe in the old "you get what you pay for" statement because I've seen too many businesses way over charge on things. But in spark plug wires, I do like to buy good silicone ones that will hold up and usually cost more. I've had good luck with Bosch silicone wires.

This makes me think back to my first model MB Jeep with flat fenders and a flat head 4 cylinder engine. For it I'd buy a 50' coil of spark plug wire from JC Whitney with a bag of ends and make my own wires.

Look in the owners manual for plugs, any good set of wires will work; don't buy the cheap ones.
