Stainless Steel Black Nitrated Intake Valves by Supertech

Set of 8 black nitrated 28.8mm standard diameter. (+1.0mm oversize available)

Fits 2007-2010 N14 Prince Engine

Production of Supertech racing valves begins with a one piece forging, where the head of the valve is forged under a slow two step process to keep a good material grain flow. The forging is then CNC machined in several steps to ensure the precision of the final dimensions. Then another heat treatment for stress relieving followed by a nitride hardening treatment (or coating process depending on the application). Lastly, more grinding, followed by our patented Superfinishing of the surface to ensure that each valve is free of any imperfections and the dimensions are precise.

Requires Supertech Keepers pn 56-595111.

Works with stock spring retainers

Inconel Sodium Filled Exhaust Valves by Supertech

Fits all MINI N14 and N18 1.6 liter Prince Engines.  Set of 8.  Standard and +0.8mm oversize valve diameter available.

INCONEL SODIUM FILLED VALVES:

Supertech sodium filled valves made of Inconel/Nimonic alloy offer a significant reduction in valve head temperatures that are required for today’s modern turbo engines. 

A cooler valve improves the material strength and durability while allowing the tuner more flexibility and a wider range of spark timing advances. Combine that with an  average weight reduction of 10% and there isn’t a cooler valve on the market
