I've known for awhile that I needed to change the spark plugs in my Studebaker. But I'd heard things. Things like you could break the plug inside your motor if you did it wrong and to be sure to tighten the plugs to the correct tension. So although I knew they should be changed, I was scared to do it on my own, and my spark plugs in there were working...right???

Without 'em, your engine wouldn't run. Without 'em working at their best, your engine won't run at its best. So as part of last weekend's wrenching adventure up at Gene Winfield's in Mojave, I changed my spark plugs...for the very first time! Gasp!

I was surprised, and a little confused, when he informed me the gap for my application was .052. What?!? While perhaps some people just throw...

Everything you never wanted to know about Spark Plugs There's alot of info about spark plugs out there, the key is knowing who to trust!

That extra efficiency can improve your fuel economy and as a bonus emissions are reduced. Choosing a plug: The first thing you want to look at when choosing a plug is your needs for your application. Plugs can range in price from $1.50 a plug for basic copper...
