I'm wondering if this is true... at auto zone I saw these plusar plugs ( how you spell it) will add a little HP and you'll get better MPG. Any one know about this? Sent from my Droid
it really depends. I have never heard of these plugs myself. But you normally wouldnt change your spark plugs until 60K miles on your car. They could be comparing it to plugs that are 40k miles old.
I have heard of them. They are basically a plug that sends a hotter spark to the cylinder, burning fuel more completely, and improving mileage. I have never used them, or known anyone that has...so I can't tell you if they work well or not. www.pulstarplug.biz
If they send a hotter spark wouldn't it be cheaper for him to gap his current sparkies bigger by a bit. Sent from my DROID2 using Tapatalk
