Review on Sinister Diesel Billet Powerstroke 2008 2010 by David Norwood

Revainrating 1 out of 5

Great idea poorly executed

The threads on both the fuel filter cap and oil filter cap were incorrectly tapped - the threads more closely resembled acme threads than traditional pipe or bolt threads. For example, the tip of the "v" thread was cut square. This way the fuel and oil filter caps are not screwed into the canisters. Still looking for a better solution than this or the OEM plastic caps.

Pros
  • Caps
Cons
  • No performance
