No matter what "spray and rinse" product you use, just make sure that you don't get any water down into the spark plug wells. Do this by making sure that you use only spark plug wires for the DeLorean and/or PRV6 engine that have the boots at the top. Plus make sure that you also have the wires properly seated so that they seal the spark plug wells. -Robert vin 6585 --- In dmcnews@xxxx, srubano@xxxx wrote: > I have used another product that is MUCH cheaper and is safe for the > enviroment.
