Review SUPERTECH For Nissan 24v Dohc Intake Valve Set 1mm Offset Nitrided

Introducing the Supertech NIVN-1052-12 Intake Valve Set, specifically designed for Nissan RB25 24V DOHC engines with a 1mm offset. This high-performance valve set is engineered to deliver improved engine response, increased power, and enhanced durability compared to original equipment manufacturer (OEM) valves.

Each intake valve in this set is made from nitrided steel material, which undergoes a unique heat treatment process. Nitriding enhances the valve's surface hardness and resistance to wear and corrosion, ensuring long-lasting performance even under the most demanding conditions.

The 1mm offset design of these valves is essential for clearance in high-performance applications. The offset reduces the interference between the intake valves and the piston crown, allowing for increased engine breathing and improved power output.

The Supertech NIVN-1052-12 Intake Valve Set also features a unique valve seat design. The seats are cut using a precision CNC machining process, ensuring a perfect fit and optimal sealing. The seats are also made from high-quality material that can withstand the extreme temperatures and pressures found in the engine cylinder head.

The intake valves in this set are also larger in diameter compared to OEM valves. Larger valves allow for more air to flow into the engine, resulting in increased power and torque. The valves are also designed with a more aggressive valve lift profile, which improves engine breathing and reduces pumping losses.

In summary, the Supertech NIVN-1052-12 Intake Valve Set is an essential upgrade for any Nissan RB25 24V DOHC engine seeking improved performance, durability, and efficiency. With its nitrided steel construction, 1mm offset design, high-quality valve seats, and larger valve diameter, this valve set is sure to deliver impressive results for enthusiasts and racers alike.
