TracTuff PRB/ PRC Swirl Pot - V1SF


The OG! This was my very first design for the K series. The tank sits just in front of the intake camshaft sensor and now includes a brace to support the tank.

The swirl pot starts with a beautifully machined 6061-T6 flange that incorporates the largest port possible within the OEM gaskets footprint, a 1/2" NPT water bypass port, and machined o-ring groove for the OEM gasket. You can choose to have a 1/8" NPT sensor port added directly to the top of the neck (near the logo) or the side (under the outlet) as well as choose from a number of accessory bung options on the tank.

I prefer this version if you have the space, because the outlet is far enough back to make hose routing a little less stressful on you as well as the product. If the product is being used in a harsh environment, I recommend you add the plinth option to help spread the load/ weight and vibration on the bracket as well as help fight some of the tugging force from bad upper hose routing. It is also a good choice for traditional side entry plenums with a large throttle body. The outlet can be moved wherever you want but the most popular choices are listed. The outlet itself can be configured for standard hose (1.25" OD) or -16 male flare.

NOTE: Made to Order - Contact for ETA - If you are interested in a specific design that varies from this, please email us at If you have questions related to the configuration or options... PLEASE visit the WHATS WHAT or FAQ page. The cap bung has a 1/16" NPT port for connection to an overflow and uses early model Honda radiator caps; such as an 88'-91' Civic/ CRX or 90'-93' Integra. If you are using AN lines, I recommend designing the upper radiator hose so that there is droop/ give... so the engines movement and does not push/ pull on the radiator and fatigue any parts.

The hardware kit includes a 1/2" NPT water bypass hose fitting, a stainless hose clamp, a 1/2" NPT plug, two stainless M6 socket head bolts, and a Genuine Honda gasket. The tank is welded so that it sits level when bolted to an engine leaned back 15° (OEM position) for the traditional option and leaned forward 8° (intake side) for the gangster lean mount option. The intake cam sensor must be swapped out for the angled version found on the K24's.
