HKS Head Gasket and Exhaust Manifold Gasket Kit for Nissan R35 GT-R

HKS Part #: 23009-AN010

SKU: 23009-AN010 Categories: , Brand:

Metal head gasket sets include the exhaust manifold gaskets. These are stopper type gasket with a 96mm bore meant for up to a 9:1 compression ratio.

To improve the performance of R35 GT-R using the factory Head gasket, the factory bore sealing proof stress restricts the improvement.
GT800 Package can release the restriction by replacing the Head gasket with the HKS Head Gasket which enables higher performance.
This HKS Head Gasket includes the Exhaust Manifold Gasket.
Best to use with GT800 Package to upgrade the engine properly.


  • High engine output parts. Designed to replace the factory Head gasket.
  • The bore diameter and thickness are the same as the factory gasket.
  • The shape of the exhaust gasket is the same as the factory gasket.
  • Improved the bore seal proof stress at high output and high boost by the redesigning the structure without upgrading the Head Bolt. (Bore seal pressure of the contacted surface was improved by 30%)
  • In-house test at 900PS confirmed the durability and safety.
  • The compression ratio of HKS Head Gasket isε9.0 which is the same as the factory ratio.
  • The Exhaust Manifold Gasket uses the 4-layer seal bead design (t=0.8). (The factory is 3-layer design (t=0.6)


  • To maintain the bore seal proof stress, the stopper’s height was changed to 0.15mm from 0.10mm. Narrowing the width enables the high proof stress with the factory Head Bolt axial tension. Also, optimizing the bead plate’s angle improved the seal pressure of the contacted surfaces of the oil and coolant seal parts without affecting the bore seal pressure of contacted surfaces. The surface of the gasket was fully coated instead of only bead part of the factory gasket’s surface like the factory gasket. Fully coated gasket’s surface can improve the rigid connection of the cylinder head and block when installing the gasket.
  • The Exhaust Manifold Gasket has the 4-layer bead plate comparing the factory 3-layer bead plate so the seal durability was improved to be used under high exhaust pressure.



●Independent Bore Stopper & Seal Bead ⇒ Separated Type
  • The bore stopper and bead are separated as placing the stopper that the tightening force is concentrated around the bore, and placing the bead around the stopper. The bore stopper load can be increased with this design, which is not possible with the factory combined type. Also, the separated type can prevent the cylinder head and cylinder from deforming since the stopper is located inside the hard bead plate.

■Performance Verification (Occupant-Seat Interface Pressure)

* HKS Head Gasket is more durable, the pressure is applied equally comparing to the factory gasket.


Bulletproof Pricing Difference

We do pricing a little differently. Every price you see includes the shipping cost to our office in Los Angeles, California. This does a few things for you; firstly it creates a built in cost savings, no hidden fees, and less hassles. The best part is we still have a price match guarantee! Click here for more information.

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions.
