Popular and Easy HEMI Mods

Just getting started? These categories are the "getting started" list for modifying your modern HEMI engine. Some are appearance oriented and some are for performance. There is something for every HEMI owner here. 
Catch Cans
Dress up your engine bay and keep crankcase blow by gas from reentering your intake air stream, intake and throttle body by adding a catch can to your PCV system. 
 
Strut Braces
Add quick style to your Charger or Challenger with a one hour appearance makeover. 
 
Throttle Bodies
Crisper throttle response and added horsepower are a bolt on throttle body away. 
 
Cold Air Intakes
The fastest 15 horsepower mod you can make. Let your HEMI breathe with a new cold air intake. 
 
Tuners
A handheld tuner can be added in fifteen minutes and optimize performance for mods you have already completed or a higher grade of fuel.  
 
Hood Pin Kits
Small-scale body updates can give your ride a completely different personality.
