ENGINE HEAT
Remains trapped inside your engine.
HEAT from the combustion process
transfers to the parts connected and
raises the temperature inside.

When your engine gets HOT
HEAT STEALS from the performance of your vehcile
leaving you with a lack of efficiency.
Negatively affecting your Horsepower,
Torque, and Longevity of your vehicle,
forcing your engine to use More FUEL.
We make Automotive Parts made from our

Revolutionary Technology of KIYLEX®.
Think of KIYLEX as a valve to let hot air out.
Reducing the HEATED Intake Air from your vehicle's engine,
Keeping your Engine Coolant temperature low and
Eliminating HEAT SOAK.

“I own a 2014 Honda civic. I averaged 28 miles per gallon. I was very skeptical of this Kiylex stuff; I filled my gas tank up 3 times, kept my receipts and wrote down my mileage from my odometer. I could not believe my new average is 42 MILES PER GALLON.”

Don Thaxton

“I drive a 2016 Acura TLX. My average fuel mileage is 24 miles per gallon. My kids told me I should try Kiylex to increase my fuel mileage. After 2 months of driving and calculating my fuel mileage I was shocked that I actually gained 14 miles per gallon! It is true what KTN says “the true power of Kiylex.

Lorene Burton

“My 2006 Acura RL averaged 22 miles per gallon. What we gained is well worth the $130 I spent on it! I would have paid more. I went from 22 miles per gallon to 31 miles per gallon.”

Fred Arden

“I got a KTN throttle body spacer for my Subaru WRX, I get 28 MPG. I was looking for more fuel mileage and some power. Being the skeptic I am, I bought one to “try it”. After it was installed I started manually tracking my fuel mileage. After a few weeks of driving my fuel mileage did increase to 37 37 MPG and my car felt like it was brand new again. An 8 gallon increase I cannot believe the difference this tiny part makes. I tell everyone they need to get a KTN spacer.”
