How does a thinner head gasket increase compression?

Reducing gasket thickness reduces the space between the block deck and cylinder head, which lowers the combustion chamber's total volume. A smaller volume for the same amount of air and fuel results in a higher compression ratio.

It refers to the gasket's two-ply construction, a layered design Spoon uses to achieve the reduced 0.46mm thickness while maintaining a reliable seal between the block and head.

Will raising compression affect my current tune?

It can. A meaningful compression increase changes the engine's detonation characteristics and may require adjustments to fuel octane, ignition timing, or ECU tuning. Confirm compatibility with your current setup before installing this gasket.

Which engine is this for?

The F20C, the engine fitted to the AP1 S2000 and shared in modified form with the AP2's F22C. Confirm your exact engine code before ordering.

Is this a difficult part to install?

Yes. Head gasket replacement requires removing the cylinder head, which is a major engine service involving specific torque sequences and procedures. Professional installation is strongly recommended rather than a DIY job.

Which S2000 does this fit?

Both AP1 and AP2, covering the full 2000 to 2009 production run, specific to the F20C engine.

Description

Spoon 2P Head Gasket for AP1 Honda S2000

The Spoon 2P Head Gasket increases compression ratio through a straightforward mechanical change: reducing gasket thickness. At 0.46mm, the two-ply construction sits noticeably thinner than a stock gasket, and less material between the block and head means less lost combustion chamber volume, which is what raises the compression ratio.

Features

Two-ply construction
0.46mm gasket thickness
Increases compression ratio

Applications

Honda S2000: AP1, AP2 | 2000-2009 | F20C

Notes

Confirm this gasket’s thickness is compatible with your engine’s current compression ratio and tune before ordering
Professional installation strongly recommended. Head gasket replacement is a major engine service; have this installed by a technician experienced with the F20C.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

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 here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
