delivery thoda slow laga but part ekdum original quality ka hai. dad ki old tacoma me lagaya purana wala kharab ho gaya tha. fluorine rubber seal ki wajah se heat ka issue nahi aayega lagta hai. engine smooth chal raha abhi to.

good oe replacement
bought this for my t100 truck emission system repair. matches the factory green color code perfectly. installation was tricky because of the crowded engine bay layout, but once bolted on it stopped the vacuum leak completely. solid build.

engine light gone finally
was getting that annoying p0402 error on my old 4runner for weeks. mechanic said change the switch valve. got this green housing one and fixed it myself. tight space near the egr so took some time to fit, but it cleared the check engine code right away.
