Do I have to cut the stock hood to fit it?

No. The duct is designed for the factory hood and needs no trimming of the hood underside. Because individual cars vary, the manufacturer notes that slight modification may occasionally be needed, and later cars also require removal of the front performance rod inside the bumper.

Can the Type-N Air Duct for AP1 cars be used with an aftermarket hood?

Yes. The Type-N Air Duct for AP1 and AP2 cars fits all hood shapes, according to the manufacturer. If your S2000 wears the Type-V vented hood from the same maker or a Mugen carbon hood, though, the wider Type-V duct is the recommended choice for those two hoods.

What is the difference between the Type-N and Type-V ducts?

The Type-V duct is wider and fits only cars with the Type-V vented hood or a Mugen carbon hood, and it cannot be used with a stock hood. The Type-N duct is the version for the factory hood, and it can also be fitted under other hood shapes.

Does it replace the factory air box?

No. It works with the factory air cleaner box, routing cooler fresh air to it. The manufacturer says this denser air reliably increases power, though it does not publish a figure, and it develops the duct as one part of balanced intake, exhaust and ignition tuning.

Is it made from real carbon fiber?

Yes. The manufacturer names it a carbon air duct, and its US distributor lists the material as CFRP, meaning carbon fiber reinforced plastic. No weight or layup details are published, so Bulletproof Automotive cannot quote a weight for the part.

J’s Racing Type-N Air Duct for AP1 / AP2 Honda S2000

J’s Racing’s Type-N Air Duct for AP1 and AP2 S2000s, listed in Japan as the carbon air duct for the normal bonnet, is the version built around the factory hood. It works with the stock air cleaner box and needs no cutting of the hood underside, routing cooler fresh air to the engine so it breathes denser air, which J’s Racing says reliably raises power. The Osaka company, a Honda specialist since 1989, notes that it fits every hood shape, yet it recommends the wider Type-V duct for cars with its Type-V hood or a Mugen carbon hood. For an otherwise stock-bodied S2000, this is the sensible choice.

Tips

Individual cars vary, so J’s Racing warns that slight modification may be needed on some S2000s. Late cars carrying the JDM codes AP1-130, AP1-135, AP1-200 or AP2 also need the front performance rod inside the bumper removed before the duct goes in. Once fitted, it serves any stage of use, from commuting to circuit days.

Notes

Slight modification may be required because of car-to-car variation

About J’s Racing

J’s Racing was established in Osaka in 1989, as VTEC engines and lightweight Civics and Integras were changing what a Honda could do, and it has built parts for Hondas ever since. The company develops engine response, suspension, braking, cooling and aerodynamics together as one system, then proves the parts in time attack, gymkhana, endurance and circuit racing. Its Fit lapped Tsukuba Circuit in 1’00.459, and its naturally aspirated AP1 S2000, the Maou car, became the company’s reference build for the Honda roadster. Every J’s Racing part is designed and tested in Japan, and J’s Racing USA in Carson, California handles distribution in the United States.

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.
