B15 (02-06) Hi-Power Medusa UEL Header QR25DE
Through continuous testing 2JR has improved the already dominate Medusa header with performance upgrades. Port changes to Oval Head Port Matched Flanges for a perfect seal - Longer runners by 4" over the V1 Medusa produce a higher mid-high rpm HP performance. The V2 Medusa is UEL (unequal length) and provides a "boxer-like" rumble at idle and under throttle. Comes with Billet Aluminum Alternator Clearance Bracket. You will need one slim fan (included) to run this header because of its size and runner design. It will bolt to the OEM midpipe or the 2JR 2.5 or 3" midpipe.
PLEASE READ!
For a quick install - select the 2JR Plug and Play Fan Wire kit. To run a single fan, you will need to cut the OEM fan shroud in half (not hard to do, it's plastic). The OEM Fan will be on the DR side and the 2JR Fan will be on the pass side. SPAL Fan is your best single option. Or you can run the Mishimoto Dual Fan with Shroud Kit.
Titanium Stud kit pictures is OPTIONAL - you must select it from the options above
To install the fan not using the 2JR PnP Fan wire kit- the factory clip has 4 wires, the top two are position (looking at where the clip is) and the bottom two are neg. Connect the blue fan wire to the top two + pos wires and the black 2J fan wire to the bottom two - wires.
Fits all 02-06 Sentras and Altimas - qr25de only.
