While I was at the dealer today getting the oil changed in my truck, I was reading a Field & Stream. I saw an ad for Pulstar Spark Plugs. I looked up the company on the internet and it seems they have a pretty interesting product. Here is a link to the website:
Has anyone ever heard about these or even maybe used them. My vehicle is listed as one of their test vehicles. According to “their” test results, they got an 8% improvement in gas mileage. That is a pretty substantial increase. Anyway, their website goes on to say that you could pay for the cost of the plugs in about 1 year.
I wouldn’t mind trying them because they have a 30 day return policy, but 30 days doesn’t seem long enough for someone to really try them out. Plus, at $25 per plug, that is a hefty investment.
What are your thoughts on these?
