Is your Toyota or Lexus feeling a bit sluggish lately? Maybe shaking at startup or burning more gas than it should? This BDFHYK ignition coil and spark plug set might be exactly what you need. This 4-piece set includes both the UF596 ignition coils and 93501 iridium spark plugs - perfect for when your ride hits around 80,000 miles and starts showing its age. The coils are seriously well-made with silicon steel, Japanese rubber, and German varnish wire - they'll last. The iridium spark plugs fire up quick and help your engine run smoother and more efficiently. Compatible with a bunch of models - Toyota Prius (2010-2015), Corolla (2009-2015), Lexus CT200h (2011-2015), and several others with the 1.8L engine.
