Are we using the wrong spark plugs?
 

I think I just bought the wrong spark plugs? :D

Yes sir

Thanks for sharing. I will freely admit I have typically run Denso Iridium plugs in my cars. Clearly I need to rethink that approach.

Switch/ E85, done.. I hate changing sparkplugs so I will stick to platiniums for durability. But if problems arise need to rethink this.

platinums dont always work best. i went from a bosch platinum to a cheap copper in my truck. it not only ran better but gas mileage went up alomst 5mpg.

use either copper or the bosch CS (silver).

Seriously!? You are going to switch the plugs in your $100K cars based on YouTube dude?

LMAO

The thermal conductivity part is true.

I did a science experiment in middle school on spark plugs.

What I found is Bosch Platinums gave off a much weaker spark than good old copper Autolites. I did other plug types in between. I did this by using my lawnmower and a rig to hold the gaps for the spark to jump. I simply moved each plug further away until no spark.

I know it was not totally controlled variable wise since me pulling the rope could have changed the magnetos strength, but I did it several times as an average.

It was a drastic difference.

They are tuners by trade......not exactly a rookie IMO.

Has this not been known for a while?

boosted/ nitrous should use normal plugs

Uh, no.

So we should be using Iridium and Platinum?

Aren't the recommended W3DPO's platin?

My mechanic buddy uses NGK BR9IX - iridium - plugs in 930s. Waiting great back if he's noticed anything, at least in hindsight, in regard to different plug types.

You need Splitfire's or E3's, a quart of Slick 50, and a cool collar, then you're good to go!...............;)

On a more serious note, here's a good read:

Slick 50! It's Teflonated!

You betcha!

And if it's Teflon, it's got to be good for anything!..........;)

Interesting...back around 98 when I had my 3.2 I switched to platinum plugs. Car ran like crap. My mechanic at that time had me switch back to copper. Car ran great plus the copper ones were a lot cheaper.

HAHA, what was that stuff that they took the oil pan off the car and sprayed water on the crank as the engine ran?

That'd top it off!

Wonder how much of that had to do with not being resistor plugs? For sure the spark would be weaker.
