LX9 3500 Competition Series Lower Intake for 3400 Upper Intake

Product Information

The stock 3500 manifolds are excellent in design, but are also restrictive from the factory. WOT-Tech manifolds have been flow tested and dyno proven (without tuning to date). Below are the numbers for a stock set of heads/manifolds, with a WOT-Tech ported 3500 head and stock manifolds to show the difference between ported manifolds and non ported as the bottleneck that they represent to your engine.

Based on WOT-Tech Competition Series Manifolds. CFM @ 28" 3.700" Bore

Competition Series

These manifolds are ported completely through on the lower and the upper is radius/bellmouthed for the best flow from your intake manifolds. The ports are matched up to each other and our ported cylinder heads for the best complete system available. This series of porting also incorporates a balanced lower intake porting method based on each runner style.

All Competition Series manifolds are cleaned, blasted, and painted unless new already.
