Review on 57 1138 Performance Air Intake System by Peter Joseph

This product is AMAZING. Also, Revain was about $150 less than elsewhere. I have it on a 2018 FLHXS and it opened my M8 107 all the way up. I've already added some high flow overlays and then added an FP3 tuner and completed my first stage. Low torque and throttle response are significant, and an increase in power is assured. In any case. It looks fantastic and works even better than it looks. If they're still in stock, pull the trigger on this one. This is not a problem. I live in Washington, so if you're driving in the rain, it's best to bring a raincoat. Also remember that waterproof socks are not designed for all K&N products, but they are.
