2021 Charger Hellcat

JLT has jumped into the Hellcat intake market with both feet. We have owned a 2016 Hellcat Charger for nearly a year now and have been testing and designing this kit the entire time.

This kit includes a fully Roto Molded airbox that uses the factory fresh air (Ram Air) inlet from the grille/headlight that also seals to the hood. We feel this is the key component that puts our kit well above the rest. Not only does this box help keep inlet air temps down by blocking the filter from hot engine heat, it also helps hold in the cool air getting rammed in from the inlet creating a high-pressure area around the filter.

Speaking of the filter, our filter is a custom-built design made by S&B. It has a built-in bell mouth for super smooth and fast airflow as well as huge 1" deep pleats for more surface area than filters that look much bigger.

The intake tube is roto-molded plastic with a huge 125mm for superior airflow and NO heat soak like metal tubes.
With a mouth of 4.5" at the throttle body end, it is ready for any larger throttle bodies that may come in the future.

MAF and IAT adaptor plates
2015/16 Hellcats have a Mass Air Flow sensor and 2017-2020 have an Inlet Air Temp sensor. We designed our kit to work with BOTH. Included in each kit are CNC machined aluminum plates, gasket and stainless screws to adapt to either model year.

Includes new roto-molded plastic heat shield to block engine heat at idle and low speed.

Each kit comes with custom-designed and water-jet cut Lexan shields that bolt to the hood grille. Not only do they keep rain from the filter, they allow the cooler rammed air to stay in the box around the filter VS just being pushed out of the grille.

RACE FILTER: The Race filter is an optional filter, this filter IS NOT FOR STREET USE! It's no filtering media, with prolonged use it will allow contamination that can damage your engine! JLT Performance will not be responsible for any damage from the use of the Race filter. Customer assumes all risk!

We wanted to do as much testing as possible, so we sent kits to some of the best in the Hellcat business.

Lidio from Alternative Auto did some testing for us with his personal Hellcat and this is what he posted on his Facebook page:

"Before the season ended for us here in MI -- we got the car out in some good and much cooler Fall air, (mid 40*s) and tested out the JLT unit and also benefit from some much cooler air. The results have turned out great so far. We ran numerous 9.7’s at over 142mph and then our very best was a 9.68 @ over 143mph… which we backed up with a duplicate run. We believe the JLT was responsible for most of these gains in MPH and ET since our previous best of 9.77 at just over 140mph. The traction was great but could have been better, so I’m continuing to not “slam” the throttle off the starting line with only about a 1300rpm brake torque. 60-foots were in the low 1.4’s and could have been in the very high 1.3s with a little more traction and pushing the car harder on the hole-shot. These numbers were achieved with a full-weight car and no front runners. All shifts have been at or just over 7000rpm for the entire 2017 season!
With no trouble at all."

"The Hellcat JLT airbox kit showed impressive gains on both the Chassis Dyno and most importantly in the real world! We expected no less from the guys at JLT! Great fit & finish as usual from his products. The new JLT kit for hellcats is now included in our entry-level performance package for the 2015+ Hellcat models.

Thank you!!
