Kameari Intake & Exhaust Valve Guides Kit 16pcs Nissan FJ20

The demands of valve guides are resistance to wear and abrasion, tolerance to high temperature, and seizure. This is only accomplished by combining two metals and precision machining the of the inside of the guide. In addition these guides only allow the minimum valve clearance so that the valves are moving properly during high RPMs.

NOTE: This kit comes with 16 valve guides for both intake and exhaust side.
