If you've got a Kohler engine that's not starting right or running rough, these ignition coils might be the fix. This is a 2-pack, brand new from AA Auto Parts, designed for Kohler 7000 series engines including KT715, KT725, SV480, SV530, and SV540 models. Part number IC7821110402, cross-references with 32-584-06-S. Basically, if your engine uses that style of coil, these will work. Ignition coils are one of those parts that can fail gradually - you might notice hard starting, poor performance, or eventually no spark at all. Having a pair means you can replace both at once (often a good idea on multi-cylinder engines) or keep a spare. The packaging is retail-style, so they arrive protected. No fancy instructions, but coil replacement is usually straightforward: disconnect the spark plug wire, unbolt the old coil, swap in the new one. If your mower, generator, or other equipment with a Kohler engine is acting up, check the spark first - and if the coil's bad, these get you back running.
