About this part

Product Details

If you're rebuilding the top end of your 1993-1997 Toyota Land Cruiser or Lexus LX450, especially for an engine build that will see higher RPMs, consider these Manley Race Flo intake valves. These are designed to handle the demands of engines operating under 8000 RPM, making them a solid choice for a performance-oriented rebuild of the 4.5L 1FZ-FE engine.

Manley builds these intake valves from a durable stainless steel, ensuring they stand up to the heat and stress inside your engine. They feature chrome stems and hard tips for improved wear resistance over time, and the swirl-polished under-head areas along with fully machined combustion faces are intended to help optimize airflow into the cylinders. The Race Flo shape is a specific design choice that can benefit certain engine builds by improving flow characteristics.

This set includes 24 intake valves, enough for your Land Cruiser's 24-valve engine. When undertaking a valve job, it's always a good idea to have replacement valve seals and guides on hand, as these often need to be replaced at the same time.
