My 1-8-4-3-6-5-7-2 V8 firing-order t-shirt has become a classic thanks to all of you who have bought them for years! Now you can add to your collection with a special edition in blue.

Think of this as nitrous blue, GM Corporate Blue, Mopar B5 blue, AMC engine blue. It all works, because all those companies, and many more, used the 1-8-4-3-6-5-7-2 firing order in their V8s. Man, it’s even the same for some Ford Blue engines if you number your cylinders like it was a Chevy or Mopar.

Wear this shirt and you’ll see how many people say, “hey, firing order—I get it!” It’s a good way to meet new car friends, and with the special blue version, you can also stand out in the crowd. Get a few.
