Four Seasons A/C Refrigerant Liquid Hose P/N:66663
Four Seasons 66334 a/c refrigerant liquid hose for the 2015-2020 BMW M4 and other vehicles is a liquid line hose assembly that carries refrigerant through the A/C system.
A leaking liquid line can show up as oily residue at the hose fittings or an A/C that blows warm air. A weak compressor, a clogged condenser or a faulty expansion valve can be behind poor cooling too, so find out which part is at fault before you buy a hose. If this hose is the cause, this assembly replaces it.
It is a direct-fit replacement for the 2016-2019 BMW M2 and the 2014-2018 BMW 328d, as well as other BMW models. If your BMW is not one of these, look up its year and engine on the Buyer's Guide tab.
