How man spark plugs in a TLX

We don't know,you will have to tell us.Your vehicle only comes with a 4 cylinder or a 6 cylinder engine,there is no 8 cylinder available for your TLX,so you will need either 4 or 6 plugs,depending on your engine size,unless you have the TLX SH-AWD Model,then it only comes with the 3.5L 6 cylinder engine.Hint: 4 cylinder>2.4L=4 spark plugs,6 cylinder>3.5L=6 spark plugs(1 plug per cylinder).you also have an ignition coil (COP) over each plug.the engine size is on the emissions label under your hood.Highly suggest taking your Acura to a Qualified repair shop for spark plug change "if" that's what you need done!
