2005 Mustang occasionally stalled starting in first gear unless you gave it a bit of gas even when new. Now I can take off at idle.

The plugs went into a van, which means it was a difficult install. The motor starts quicker and runs wirh morw power.

Comments about Pulstar Platinum Pulse Plug:

I've used Pulstar plugs in the past and the old ones finally had to be replaced so I bought them again because I know they work. They do what they say they do. The power gain and mileage may be small, but it's still noticeable.

I have changed over all my vehicles to this plug and all have increased in mpg, power and ease in starting even the coldest winter.

I bought these for my '02 Silverado with the 5.3L. After 10k miles of driving I have to say "these things are great". I've put 153k miles on this truck and I know exactly how many miles to the gallon I can expect in my everyday driving and while on the highway. I have been getting a true 1 mile to the gallon increase in my everyday driving and 1.5 miles on the highway scine installing these plugs.

I bought these Pulstar plugs for my 98 Buick Lasabre hoping for improved gas mileage & performance, What I did get was decreased gas mileage. The EGR valve was also bad along with a few other things, Once I had everything else fixed I noticed a slight miss in the engine at highway speeds, but not enough to set off the misfire sensor. Since I had new plugs and wires I did not suspect that was the problem, but a mechanic told me to recheck the plugs[...]the plug gap dimension (.40) Then pulled each one and checked the gap. 4 out of 6 were set at (.15) and they are supposed to be set at the factory. I re-gaped them at (.40) and reinstalled them one at a time. Restarted the engine and it ran even worse, setting off the check engine light. I then reinstalled cheaper platinum plugs, checking to make sure they were all set at (.40) which they were. CAR RAN FINE. By the time I had found the problem the 30 days were past and I was out [$]bucks.
