Holley is pleased to announce the release of their new NOS wet nitrous system for 2015-2020 Challenger/Charger Hellcats and 2018-2020 Trackhawks! While the supercharged Gen III Hemi Hellcat engine is potent, NOS felt that it could still benefit from a 200 hit of spray! This new plate fits between the throttle body and supercharger and delivers up to 250 additional RWHP when desired.
