Maximum Flow for the 6.4L HEMI: Corsa Apex Metal Intake With MaxFlow 5 Oiled Filter
The Corsa Apex 616964-O combines an all-metal intake tube with the MaxFlow 5 five-layer oiled cotton gauze filter to deliver premium cold air performance for 2012 to 2017 Jeep Grand Cherokee SRT8 and SRT models with the 6.4L HEMI V8. The 616964-O carries CARB EO number D-803-2, certifying it for legal use in California and all 50 states. The Apex metal tube resists heat absorption better than polyethylene alternatives, maintaining structural rigidity in the Grand Cherokee's engine compartment. Paired with the MaxFlow 5 filter's 98 percent filtration efficiency and proven free-flow design, the 616964-O reduces intake restriction and delivers measurable horsepower and torque gains on the naturally aspirated 6.4L V8 with a direct bolt-on installation requiring no ECU tune.

Frequently Asked Questions
What is the Corsa 616964-O?The Corsa 616964-O is an Apex Series all-metal MaxFlow 5 cold air intake for 2012 to 2017 Jeep Grand Cherokee SRT8 and SRT models with the 6.4L HEMI V8. It carries CARB EO number D-803-2 and uses a MaxFlow 5 oiled cotton gauze filter for 98 percent filtration efficiency with measurable horsepower gains on the 6.4L HEMI.
Is the 616964-O legal in California?Yes. The 616964-O carries CARB EO number D-803-2 and is legal for sale and use in all 50 states including California.
What is the difference between 616964-O and 616964-D?Both share the same Apex metal tube, housing, and CARB certification. The 616964-O uses a MaxFlow 5 oiled cotton gauze filter serviced every 25,000 miles, while the 616964-D uses an oil-free DryFlow filter washed every 50,000 miles.
Does this fit the 2014 and newer Grand Cherokee SRT?Yes. Jeep renamed the trim from SRT8 to SRT for 2014. The 616964-O fits 2012 to 2013 Grand Cherokee SRT8 and 2014 to 2017 Grand Cherokee SRT.
Does the 616964-O require a tune?No. The 616964-O is a direct bolt-on intake with no ECU tuning required.
How often does the MaxFlow 5 filter need service?Re-oil the MaxFlow 5 filter every 25,000 miles and wash and re-oil every 40,000 miles using a compatible filter care kit.
Why is a metal tube better than polyethylene?Metal tubes maintain their shape more rigidly under high engine bay temperatures and resist deformation. They also radiate rather than absorb ambient heat, which can help keep inlet air temperatures lower during extended high-load operation.
How long does installation take?Installation typically takes 30 to 45 minutes with basic hand tools. All hardware is included in the kit.
