how does spraying the spark plugs and wires and spark plug gaps on he engine with loads of WD40 affect a car? In positive ways, or negative ways?

Is it conductive? damaging? what will happen?

Just for openers: the WD in WD40 stands for Water Displacement and it actually was the 40th formula that the maker(s) developed that did what they were looking for. It is not conductive. I remember when the product first hit the market. I was at a trade show and the distributor had an electric motor running in a glass tank filled with WD40. Not only was the motor running but of course it was running a lot cooler than if it were in air. JC

In the old days, we would spray down the distributor cap, coil, and wires if you got the engine wet and it wouldn't start; from either washing the engine compartment or going through a big puddle.

However, I'm not sure if that is recommended these days with modern cars.

I wouldn't recommend this on many modern day cars, especially the millenia with so much under the hood

well this is actually reffering to my 1988 929. I wanted to buy new wires to go along with the new spark plugs me and my dad were putting in cos the old ones were dirty, but my dad said dont be stupid this will clean them right up so he got wd40 and sprayed in the gaps where the spark plugs would fit WITHOut the spark plugs there (umm isnt that bad cos wd40 breaks apart oil and thats going straight in the engine?) the spakr plugs themselves, and the wires...

It's not going to hurt them. However, it's not going to help either. If the wires need to be replaced, spraying them with WD40 is not going to fix them.

I think you are refering to the spark plug "boot", that you sprayed WD40 into. If you had water or moisture in the boots, then spraying WD40 in there would displace the water (replace the water with WD40). Which would be a good thing, because that is what WD40 is made for.

However, other than displacing the water, WD40 is not going to do any much else for you. It is not going to make "old" plug wires "new" again.
