When it comes to performance upgrades, the Manley 34mm Race Flo Intake Valve is a standout choice for Nissan 3.0L VG30 engines manufactured between 1990 and 1996. With over 40 years of experience, Manley Performance has built a reputation for crafting top-notch stainless steel valves that are engineered to excel in demanding environments.
The Manley 11106-12 intake valve is designed with precision and performance in mind. Featuring a head diameter of 34mm and a stem diameter of 6mm (0.2362 inches), this valve is crafted from a unique "Race Series" alloy that ensures durability and efficiency. The chrome stems not only look great but also provide enhanced resistance to wear and tear.
What sets Manley valves apart is their ability to outflow and outperform competitors, even in severe conditions. The valves feature swirl-polished underheads and fully hardened tips, ensuring they maintain their integrity and performance under pressure. The "Pro-Flo" design reduces the stem diameter in the fillet area, which not only enhances airflow but also reduces valve weight, making it a perfect fit for both street and race applications.
This intake valve is specifically tailored for the Nissan 3.0L VG30 engine from 1990 to 1996, making it an ideal upgrade for enthusiasts looking to boost their vehicle's performance. It's crucial to check your valve guide size to ensure proper valve stem-to-guide clearance, as guides may need to be honed when replacing stock factory valves.
Customers have praised the Manley 34mm Race Flo Intake Valve for its superior quality and performance enhancements. Many have noted improved throttle response and increased horsepower after installation. Here's what some users are saying:
"After swapping out my stock valves for the Manley ones, I noticed a significant difference in power delivery. Highly recommend!"
"These valves are built to last! The quality is evident, and the performance boost is real. A must-have for any VG30 build!"
If you're looking to upgrade your Nissan 3.0L VG30 engine, the Manley 34mm Race Flo Intake Valve is an outstanding choice. With its high-quality construction and performance-oriented design, you can trust that this valve will help you achieve your automotive goals.
Note: Always verify your vehicle's specifications and valve guide sizes before making a purchase to ensure compatibility.

Manley Performance, formerly called Manley Speed Equipment, was established in 1966 by Hank Manley shortly after his graduation from Brown University. His interest in the performance and racing traced back to 1960 when, at age 17, he rebuilt a 312 CID Ford V8 engine, installed a camshaft and three two-barrel carbs, and raced a ’56 Thunderbird on New Jersey’s streets. Initially, the company’s product lineup included stainless valves, lifters, camshafts, forged pistons, vanadium valve springs, pushrods, and timing chain kits. By 1998, Manley had outgrown its first Bloomfield, New Jersey facility and bought several acres in Lakewood, New Jersey. It was around this time that the brand’s name formally changed to Manley Performance. Nearly a decade later, the production space doubled in size.
Evolving in the Automotive SpaceLed by GM Michael Tokarchik in 2002, Manley entered the high-performance passenger car market as an OEM supplier of connecting rods for the 2003/2004 Ford SVT Mustang Cobra. Production reached 2500 rods per week without missing a single delivery date. Ford awarded Manley its highest ever supplier rating. Manley’s presence in the OEM market continued from there as a supplier for the Ford GT. After nearly 50 years since its inception, Manley continues to be globally recognized as the leading manufacturer of performance valves, connecting rods, cylinder head components, pushrods, drive and oil systems, and several other engine parts.
What is Manley’s Specialty?Manley Performance specializes in high-performance engine internals that range from stock replacements to full-on race applications. They have been the standard of the industry since their inception; a fact that still remains true now as they have ventured into new markets. Today, Manley Performance continues to re-define itself in a high-performance aftermarket industry that is constantly evolving. The brand has developed a wide range of new products for growing markets that include sport compact, Ford modular, and Chevy LS. Manley also maintains its leadership role with the traditional V8 engine business.
