JLT Performance was founded by John and Lisa Turner in 2004 with a single cold air intake for the ''Terminator'' Cobra's supercharged 4V 4.6L engine. The design worked flawlessly and JLT exploded into the cold air intake market with a whole slew of designs for basically every single Mustang model on the road. JLT continues to churn out some of the most powerful Mustang cold air intakes available that add on loads of horsepower and torque. JLT expanded their manufacturing repertoire to include carbon fiber engine dress up items and high-quality oil separators.
JLT builds and ships all of their parts out of their Chesapeake, Virginia location for ''Made in the USA'' quality.
