NGK TR-55 are what most people use, assuming you are not spraying nitrous or have any other power adder

For an NA application, we typcally put in TR-55's and then TR-6's for cars with light poweradders. We have both on the shelf ready to go. Being in TX you can have them in a couple days, no problem!

Typicaly cars that are cam only and stock use the TR55.
Cars that are power adds or hi compression like to use the TR6.
On avg we sell 6 sets of tr55's to every 1 set of TR6
We always ship USPS prioriy mail for 2-3 day delivery to any US state or territory.. Yes even Hawaii and Alaska.. Puerto Rico, Guam would be a good test. I carry them in stock at all times 18.68 for plugs only shipped to your door or with my MSD wires gauranteed for life $61.20
