The Ngk 1422 is a plug many of us used back in the 2013-2014 time period until the HKS plug took over as the best plug to use. This is a good cheap alternative to get you by until you can afford the HKS plugs. If you changed these plugs often you shouldn’t run into any issues with these plugs. We at Kdm Tuners still prefer the Hks M series and the Ngk Race Series plugs for all tune and high hp cars.
