Howe Update Reservoir Neck 4.0 with Radiator Cap and 90 Degree Fitting (1017-1006)

The 4.0 version of Howe's update neck, complete with radiator cap and 90 degree fitting. Compared with the plain new-style neck (1017-1035), this one saves you from sourcing those two parts.

• Size: 4.0
• Includes radiator cap
• Includes 90 degree fitting

Good for updating an older 4.0 reservoir.

Howe Performance part number 1017-1006.
