5-Ply Silicone Hose Straight Reducer (3"-2.75", 3.5"-3", 4.5"-4")

Custom 5-ply silicone, not a standard hose. We have these made to our own spec with 5 plies of reinforcement and a thick wall. Most off-the-shelf hoses are 4-ply with a 4 to 5mm wall. The extra ply and thicker wall hold their shape under clamp pressure and last longer in engine bay heat.

Use a straight reducer to join two pipes of different sizes in a straight line. The 3" to 2.75" is the same reducer we ship with our NP300 twin, N70, N80 and N90 airboxes.
