Wrong spark plugs....

My trucks parked on a busy street or else i would crawel under rn and show you lol

But its a big black box with alot of hoses coming off it. Prety hard to miss and fairly easy to access

 

Yeah I found it.. only way to access most of it is to drop the tank, or jack it up..

I'm wondering if all those hoses and stuff around the canister are safe to spray with soapy water. I mean, water gets under there when it rains, and the system should be sealed (air tight).

Thinking I'll spray soapy water on it and start the truck... Last resort, take it somewhere for a smoke test.

P.s. sure wish the canister was still in the engine bay.

 

I believe some are under a vacuum so its best to smoke test

 

If they were the right plug for the application, yes they would have been fine. They wouldn't have gained you any performance though. Technically the cheap copper plugs conduct better so if anything they should perform better, however there's not enough difference that you would notice. Like I said, the fancy iridium plugs are just made to last longer. That's why they put them in all the new stuff so they can claim no service required for 100k miles.
