Anybody have any advice on changing spark plugs?
I have a '99 Mazda 626, and, although I can reach all the spark plugs, the 3 in the back I can't seem to grab even with an extension.
I've only had the car about a month and I'm trying to do most of the work myself ( as possible). I've changed the spark plugs on other cars, but I'm afraid to force something.
Thanks!

 

How long of an extension are you using? An 11" should reach the spark plugs just fine. You are, I hope, replacing with NGK or Denso.

 

Hmm, I don't think I used an 11" extension. Maybe that was the problem.
What different about the NGK and Denso plugs?

 

NGK and Denso spark plugs are OEM (Original Equipment Manufacturer) plugs. They are designed to give the best performance and durability in your car. Do not use whatever the guy at the parts counter is trying to sell you to make a sales quota.
