Product Information

P2R CNC Ported Cylinder Heads – High-Performance Upgrade for J-Series Engines

P2R CNC-Ported Cylinder Heads are engineered for serious Honda and Acura J-Series performance builds, where airflow, reliability, and consistency matter. Each set is sold as a matched pair and is available for all J-Series engine families, including J25, J30, J32, J35, and J37.

Every cylinder head starts with our proven CNC porting program, developed through extensive flow bench testing, dyno validation, and real-world racing. These CNC-ported J-Series cylinder heads have been used on race cars worldwide, including some of the fastest J-Series-powered vehicles in the world, delivering repeatable, measurable performance gains.

Whether you’re upgrading a street-driven Honda or Acura, building an all-motor J-Series race engine, or assembling a high-boost turbo setup, P2R offers multiple cylinder head packages tailored to your performance goals.

Depending on location, shipping generally takes 1-5 business days within the continental US and 3-10 business days in North America.  Items shipped international can vary with updated estimated timelines by shipping carriers heavily dependent on inbound/outbound customs of respective country.  Transit times will vary dependent on the size and weight of product and method of shipment chosen at checkout.  You will be notified if the shipping time frame is longer than expected due to product availability.  Please inspect all shipments immediately upon receipt.  Due to carrier guidelines we cannot accept any damage claims more than 7 days after receipt.

Returns only accepted with written approval and RMA number from Throwdown Performance within 14 days of receipt.  Items must be returned in new, resellable condition.  Most returns are subject to a 15-25% restocking fee that cannot be waived, and is subject to change depending on manufacturer.  Many items, not limited to the list below are not eligible to be returned including:  Special order items included wheels, chassis bracing, electronics, custom built items, clearance or open items, body parts, oil and aerosols, used or items missing pieces, and other custom ordered or imported items cannot be returned.  Actual shipping fees paid both to you and back to Throwdown Performance or manufacturer will not be returned.  In cases of free shipping promotion, actual shipping fees will still be assessed on shipment.


 

Cancellations:

Cancellation requests can be sent to us via email and cannot be guaranteed until an item is fully refunded and confirmed.  Due to multiple distributors, please do not consider any order cancelled until fully refunded to your account (this includes any customer or Throwdown asks or requests to cancel an order).  We attempt to get all items to our customers as quickly as possible and ETA's may change without notice and most items will not be able to be cancelled post being processed.  Many items including those custom ordered are not eligible for cancellation.  All cancellations are subject to a cancellation fee of 10% of the total order value.
