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.Designed to fit and work with the stock manifold as well as the BOSS and Holley Sniper.

It starts with a 4" opening at the throttle body to match up to those 90mm units. The kit comes COMPLETE with 2 couplers. One 4" straight for the 90mm and a 4-3.5" 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&B filter. A massive 5" at the inlet with a full radiused bellmouth to huge 1" 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 coolest 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.

It’s a full 112mm ID at the MAF area
MAF is rotated to the inside or engine side of the tube for a more pleasing smooth look

Includes roto-molded plastic heat shield to block engine heat at idle and low speed.
It incorporates the fresh air inlet from the grill.
It uses a large area to make sure the filter has tons of cool air.

30-35 RWHP from stock with custom tune (gains from both tune and intake)
2-4 RWHP over our original JLT CAI on a stock GT
8-10 RWHP over our original JLT CAI on a BOSS!
10-14 RWHP over our original JLT CAI on a modded GT
We have tested this on three different cars with different stages of mods and all gained over the original kit. 

A JLT specific tune is required with this kit.
