Remove the spark plug washers or not?

I used to hate stuff that came from Japan (such as NGK spark plugs) for no good reason, myself. Fortunately I outgrew that blinkered mindset.

Lodge "Fire Injector -- Run Your Car Without Spark Plugs" spark plugs, eh! Nifty. I might've kept 'em on the shelf as curiosities rather than installing 'em, but I imagine they're fairly plentiful on eBay.

I heard that they are of good quality...I just know they are pink :)
