No real impact I think Bill.

THe issue here is what is "inside the engine compartment" since our rules allow the pickup of air there, or in the stock location.

To me, the radiator has to be the forward definition of the engine compartment. Otherwise, you could use the void between the grill and the radiator on pretty much any car to make an effective and never intended cold air intake.

Based on that, he Jackson intake is not legal as it extends past the rear of the radiator. Cut it off there and probably legal.
