Brand new in original packaging, TORNADO Air Management System Air Filter Inlet Insert ki-90. Average 1-2 more miles per gallon plus may deliver more power.

Tornado is a non-moving part, designed to enhance fuel economy. Product should fit snug and tight, and must not be loose. Its air flow dynamics create swirling, fast-burn effect in the combustion chamber, thus creating finer particles (atomized fuel), allowing better flame propagation and more complete combustion.

ki-90 measures 90mm in diameter by 40mm in length/heighth. Stainless steel.

Easy to install. Directions can be found on the back of the box or on the product website, Tornadoair.com
