I bought this 12 Valve Turbo Diesel shirt for my birthday gift. The first time out in public I could feel all the eyes on me. From diesel enthusiasts to women who knew that a 12 valve Cummins Turbo Diesel is the best engine ever fitted in a pickup truck. I'm a married man and to others I say purchase with caution even a wedding band isn't signage enough saying off limits once this shirt is donned. I have washed it many times and the fabric is still like new, fits great.
