Celebrating 40 years of horsepower, hustle, and heritage.
This isn’t just a T-shirt — it’s a statement. The Heritage T is Industrial Injection’s limited-edition tribute to four decades of diesel domination. Built for the true gearheads, wrench warriors, and performance junkies, this shirt combines premium style with hardcore attitude.
Ultra-Soft, High-Quality Material – Feels like a cloud, fits like it was custom made for you.
Perfect Fit – Tailored to move with you, whether you're under the hood or out on the town.
Timeless Style – Looks killer at the track, shop, office, or your favorite watering hole.
Exclusive Design – Featuring throwback graphics and bold industrial vibes.
Once it's gone, it's GONE. No restocks. No reruns. When these shirts sell out, they’re history — just like the 40 years that got us here.
Made for all-day comfort and all-night attitude
Engineered with the same passion we put into every injector and turbo
Elevates your shop gear game from basic to legendary
Colors: Black with Red + Grey Heritage Print
Ships Fast. Wears Hard.
Limited Edition – Don’t wait. Don’t blink.

When you purchase a product from our website that has a core requirement, you have two options:
1. You choose to pay the core charge and we will ship the product right away, then once we receive the cores you will be refunded the core charge if your cores pass our inspection qualifications. This is the preferred choice and has the least delays.
2. You choose to send in your cores before we ship the product that was purchased. This choice has the risk of delayed shipment of your purchased product and our inventory is not guaranteed by the time we receive your cores. You will need to follow all of the instructions below as quickly as possible so that you can get your purchased product and we can receive the cores. When you choose this option you acknowledge that by the time we receive your cores, our inventory could have change and there could be a delay in your shipment.
INCLUDE RA# THAT WAS ISSUED AT TIME OF PURCHASE! If RA # is lost, please call Customer Service at (800) 955-0476. Have your original invoice at time of phone call to give all appropriate information for return.
Core return freight is the responsibility of the customer
FULL CREDIT WILL BE GIVEN WHEN:
In order to receive full core credit, your core(s) must be returned within 90 days from receipt of order. It must be as is “off the engine.” Full core credit will be given if core meets acceptance criteria. Cores that are damaged during shipment to Industrial Injection are the responsibility of the customer and their shipping company.
NOTE: packages that have fuel or oil residue on the outside of the box during shipping will not be delivered by UPS or the postal service which will cause delays.
PLEASE RETAIN RA#, INVOICE # AND TRACKING NUMBER UNTIL CREDIT IS RECEIVED BY YOU. We do not research by customer name, only invoice # or RA #.
