How well does this work when riding in rain? Does it require a rain sock? I'm changing stock 2 into 1 to Rinehart duals with a Cobra tuner and want to increase intake.
Jerry on Jul 7, 2019
BEST ANSWER: It works well, a rain sock may be helpful in a heavy down pour where most will pull over anyway

I installed this breather on my tri glide in about 30 mins.. I am very pleased with the way my Harley breathes after the install . The increase in power was very noticeable . I definitely recommend this product.
