We received some information on K&N’s cold air intake system for the new 2008 Dodge Challenger SRT-8, part number 63-1114. The dyno graph shows a very impressive peak gain of 32 horsepower. To come up with this performance increase, K&N replaces the Challenger’s original intake assembly; including the air box, air filter and intake tube with an new intake design. The aftermarket system brings in air through a K&N High-Flow Air Filter that increases airflow and filtering capacity.

Protecting the chrome top cone-shaped air filter, and isolating it from engine heat, is a powder coated steel heat shield that replaces the Challenger’s stock air box. The air travels through a K&N Roto-Molded Polyethylene Tube that is formed and shaped, in the design phase, to drive a more laminar flow of air to the Challenger’s 6.1L V8 engine.

It should be interesting to see how the Challenger SRT8 performs at the track with the extra 32 HP, we would also be interested in seeing some other dyno graphs showing any torque increases as well. So far we have a couple of Challenger SRT8’s in the database running low 13’s at 108 MPH in the 1/4 mile. Click on the dyno graph below to view the details:
