Suggest you check into the Workhorse forum on www.irv2.com. There is a wealth of information on how to correct the poor airflow some of the coach builders have made.

Here is a link to the best high temperature spark plug wires for your engine. These will be the last set you will need to buy. They do have a kit to direct more air flow to your spark plug wires, but it is easier, and cheaper, to just install wires that will not be affected. This is caused by your coach manufacturer not making the front openings sufficient to provide good air flow. Some manufacturers do a good job but others created a problem with their front end design. Some also have a problem with water getting into the air intake, if the front end is not designed according to Workhorse specs. Taylor Extremes

On mine I pulled the asbestos liner out and created a duct for air to flow through. Also reinsulated my doghouse cover with some heat resistant dynamat.

Though the air flow problem is caused by bad BODY design and thus is NOT a Workhorse problem (it is a "Make of coach" problem) Workhorse did develop a solution. Alas, I do not know what it is. (Since I do not have the problem).

The suggestion to visit the Workhorse forum on IRV2,, is hearby seconded. I know for a fact that Workhorse has people (at least a person) who reads it at least on occasion, I have talked with him eye to eye, shook his hand, talked over a few of his posts and the like. NO, I won't say who he is.


Home is where I park it.

Really all you need to do is contact a Workhorse service facility IF you want to spend the money. The airflow kits is readily available. Airflow kit
Chances are if you know that you have a problem already, you still have to buy a new set of plug wires.

Build an air dam.

Years ago there was an article in motorhome magazine about this. I did just that on an 89 p-30 chassis I had at that time. I enclosed the area behind the bumper and radiater with some sheet metal I had laying around and foamed up all the cracks and forced all the air through the radiator, instead of letting it spill out below. Big difference.

Problem was, that sucker oil canned like mad till I added some angle iron stiffeners,

So some heavy duty rubber sheeting would be recommended.

I had the Airflow kit installed along with new hot wires at Joe's Truck and RV in Lake Havasu. All is well now. Workhorse paid for it. This was three years ago. The air ducts were mounted on the lower "bumper" .. we cut the holes in the fiberglass about 6inches tall by 8 or 9 inches wide each. The ducts were mounted and the hoses connected behind.. Looks kinda NASCARish.
