JLT Super Big Air Kit 2011-14 GT with Roush/Whipple/FRPP Supercharger Tuning Required Recommended for 800+ RWHP


All New JLT Series 2 for 2011-2014 Mustang GT 5.0 and 2012-2013 Boss 302. Have an aftermarket manifold like a Boss or Sniper? Then this is your cold air Intake! This new kit was Designed from the ground up to work with today's aftermarket manifolds and throttle bodies.

Released back in 2010, our original kit has worked great on the 5.0 for over 7 years. With the release of the BOSS and now the Holly Sniper along with 85 and 90mm throttle bodies we decided to do a reDesign to accommodate these different sizes and angles.

The all new JLT Series 2! Bigger, Badder and still the Best! Designed to fit and work with the stock manifold as well as the BOSS and Holley Sniper. It starts with a 4 inch opening at the throttle body to match up to those 90mm units. The kit comes Complete with 2 couplers. One 4 inch straight for the 90mm and a 4-3.5 inch reducer for the stock unit.

Next is the perfect 112mm MAF housing. Up from 107mm on the original, but not so big to cause drivability issues. Oh and the MAX allowed in NMRA Coyote Stock racing. At the MAF you attach our one off Designed S and B filter. A massive 5 inch at the inlet with a full radiused bellmouth to huge 1 inch deep pleats, this thing flows tons of air.

Finally all this sits in our own Designed Roto Molded Heat Shield that utilities the factory fresh air inlet to get you the most cool air possible. Finish it off with a silicone coupler and stainless clamps and you got the BEST Intake on the market!!! No Metal Tubing Here!!
