The plumbing is excellent, the solenoid valve is anemic. I bought it and it was weak. Read reviews about a faulty valve. I had to replace it with a 3/8 solenoid and a 3/8 female to 1/4 male adapter, which effectively turned the air horns into beasts. The powerful sound of a screeching horn is enough to just touch the steering wheel cover. Make sure you remove the nipples (yes they are rrmovanle and they unscrew and they can be swapped right or left as well) so the solenoid valve can be installed.
