shipping by JP was horrible. Air filter cleaner broke open and spilled all over in the box.

Great product but terrible packaging. Everything was in one big box with little packing material. Half of the bottle of filter cleaner had leaked out. I will not be purchasing from jp cycles again..

Worked great, sprayed filter all down, let it soak and drain, the repeated about 3 more times, sprayed down with cold water to clear out the rest of the debris, let dry overnight. Engine is running much more smoothly.
