Manley 93-98 Toyota Land Cruiser 4.5L (1FZ-FE) 39.5mm Race Flo Intake Valves - Set of 12

These Manley Race Flo intake valves feature a 39.5mm head diameter, a specific design choice aimed at optimizing airflow for your 1993-1997 Toyota Land Cruiser or 1996-1997 Lexus LX450's 4.5L 1FZ-FE engine. When you're rebuilding the top end, especially if you're looking to get the most out of your engine's breathing, valves like these make a notable difference. They are constructed from high-quality stainless steel, which is a solid choice for durability under the heat and stress of engine operation.

Manley has given these valves chrome stems and hard tips, adding to their wear resistance and overall longevity. The under-head areas are swirl polished, and the combustion faces are fully machined. This attention to detail helps smooth the path for air entering the cylinder, potentially improving combustion efficiency. While these are listed as Race Flo shape, Manley offers other shapes for different engine builds, but this specific design is well-suited for engines operating under 8000 RPM.

This set includes 12 intake valves, enough for your 1FZ-FE engine. If you're undertaking a significant engine overhaul or rebuild, these well-built valves are a popular choice for those seeking improved performance from their Land Cruiser or LX450.
