1990-1992 ZR1 Bosch Platinum Spark Plugs Car Set
If you’re running a 1990-1992 ZR-1, you already know that the LT5 doesn’t exactly take it easy on spark plugs. These Bosch Platinum Plus plugs are built for the kind of abuse only a ZR-1 owner calls “spirited driving.” They’re designed to handle hour after hour at max output without fouling, misfiring, or crying for mercy. The platinum core lights off quicker, keeps acceleration smooth, bumps fuel efficiency, and reaches self-cleaning temps in seconds so you spend less time worrying about plugs and more time enjoying that glorious wide-open throttle. Add in lower ignition voltage needs, corrosion-resistant nickel threads, and a long-life ground electrode, and you’ve got the plug that keeps your ZR-1 firing like it should.
