Made a big difference in performance in my 21 RT in cooler temp by a few degrees better fuel mileage and acceleration easy install to about 30 min to install .one clamp to the throttlebody was to long I had to cut down shorter .I recommend this product
2011 rt charger self install
Fits right in after pulling out the factory intake. Looks great.
Very big fan of the dry filter. No need to oil up a new filter every few months.
Would recommend
