Bourne HPP K-Series Valve Spring Set

Experience the power of the BOURNE HPP K-Series Valve Spring Set, meticulously designed for N/A builds to handle 200-350 bhp. This top-tier spring set is a game-changer for your engine, offering a smooth and efficient performance. With its standard fitment and compatibility with original platform shims and retainer setups, it's the perfect upgrade for your vehicle. The valve spring diameter matches that of the original Honda Type-r valve springs, allowing for a seamless upgrade without altering the spring bases or retainers.

Product Specifications and Benefits

This valve spring set is an excellent choice for those looking to enhance their engine's performance with most aftermarket camshafts, especially those with a maximum lift of 14mm or less. We recommend this kit as a refresh option for engines with high mileage or softening valve springs. To ensure a hassle-free installation, the kit includes the following:

  • Bourne HPP valve spring set
  • Honda OEM NEW spring bases
  • Honda OEM NEW steel retainers

Practical Applications and Target Audience

Whether you're a street car enthusiast or a track racer, this valve spring set is a versatile choice. It's ideal for engines not exceeding 9,000 rpm, making it perfect for daily drivers and track cars. The use of steel retainers, despite being heavier than titanium, is a strategic choice for endurance and strength, ensuring long-lasting performance. This kit is tailored for customers with Type-r cylinder heads or those looking to upgrade from non-Type-r cylinder heads. Embrace the power of the BOURNE HPP K-Series Valve Spring Set and take your engine's performance to new heights.
