The Kinugawa Ball Bearing TF06-18K turbocharger is the #1 best-selling bolt-on upgrade for the Mitsubishi Lancer EVO X (4B11T), delivering 500+ HP with a third-order free-surface billet 18KX compressor wheel (55.1/75mm, 54 lb/min), STS Advanced Dual Ceramic Ball Bearing, and a Hi-Ni 22% thermal-resistant turbine housing — all backed by Kinugawa's 1-Year Trouble-Free Warranty.

"The turbo makes the power curve much smoother and pulls to redline — faster and easier to drive daily. Worth every penny. Someone usually makes the mistake of going too large and losing mid-range without the 18K!"
