TracTuff PR3 Swirl Pot - V1


The swirl pot is the top choice for PR3 (B16A/ B16B/ B18C/ B18C5) cylinder head cooling system upgrades! Best solution for systems that have tucked radiators, a radiator without a cap bung or for situations where you want a higher fill point to aid in burping the sometimes troublesome cooling system. 

The swirl pot starts with a beautifully machined 6061-T6 flange that incorporates incorporates a 3D tapered exit port for a seamless transition to 1.25" tubing. The backside of the flange has an o-ring grove for a positive seal without the hassle of Hondabond. The V1 PR3 swirl pot clears the VTEC spool valve assembly, distributor, and heater nipple. A bracket extends to the oil pressure test port on the front of the cylinder head to support the cantilevered weight. The OEM crush washer goes between the bracket and the cylinder head. The outlet 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 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. Due to tank placement, the heater nipple may conflict with an accessory bung if you choose to hide it on the backside of the cylinder (like shown).

The swirl pot includes two stainless M6 socket head bolts and an o-ring. The tank is welded so that it sits level when bolted to an engine leaned forward 5.5° (exhaust side).
