Does the Intake Kit for CL9 TSX cars fit the 2009 and later TSX?

No. HPS lists part number 837-122 for the 2004-2008 Acura TSX 2.4L only. The second-generation TSX that followed from 2009 is not on the HPS application list for this kit, which is shaped around the first-generation car and its 2.4L engine, so check the model year before ordering.

How much power does the intake add?

HPS quotes dyno gains of 11 wheel horsepower and 9.9 lb-ft of torque for the 837-122 kit, along with sharper throttle response, and states that the system keeps a safe air fuel ratio. The TSX is the only car this kit is built for, so those figures relate directly to it.

Does the intake need a tune?

No. HPS states that the 837-122 kit does not require tuning and does not trigger a check engine light. The K24A2 keeps running on its factory engine management, and HPS also states that no modification is required during installation, which follows a step-by-step manual with clear pictures.

Can the kit be converted to a shortram?

Yes. HPS designs the 837 Series so the system can be converted into a shortram setup, keeping the filter inside the engine compartment instead of outside it. HPS does not list the conversion steps on its product page, so ask Bulletproof Automotive before ordering if a shortram is the goal.

Which finish does this listing come in?

Red, part number 837-122R. Some photos show the same Intake Kit for CL9 TSX cars in blue, polished and black finishes for reference, but those finishes are not offered on this listing. The red tube ships with the same filter, couplers, clamps and hardware as every other finish.

HPS Cold Air Intake Kit for CL9 Acura TSX 2.4L

HPS’s Cold Air Intake Kit for CL9 Acura TSX 2.4L cars has dyno numbers behind it: HPS recorded gains of 11 whp and 9.9 lb-ft of torque after swapping the factory air box for a 2-3/4 inch mandrel-bent aluminum tube. The washable filter moves outside the engine compartment to breathe cooler air, and the 837 Series design can be rebuilt as a shortram later. It suits first-generation TSX owners who want a proven bolt-on for the K24A2 that keeps the factory tune.

Design and Performance

Eleven wheel horsepower is a worthwhile result for an intake alone on a naturally aspirated 2.4L, and the filter position is a large part of why: drawing air from outside the engine bay keeps it away from engine heat. The trade-off is a longer tube with the filter out of sight. Owners who would rather see and reach the filter under the hood can convert the kit to a shortram.

Features

Mandrel-bent aluminum tube in place of the restrictive factory air box
Relocates the filter outside the engine compartment for cooler intake air
Converts to a shortram layout if the owner prefers the filter in the engine bay
Washable, reusable HPS Performance air filter
Reinforced silicone couplers with 100% stainless steel T-bolt clamps

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.
