When I had this car and used the default tune from HKS I decided to buy the HKS spark plugs. The only reasoning I had at the time was because that’s the part they used for their testing and I trusted the brand. (And I wanted something to play with on the car)
After taking out the factory plugs I noticed they were a bit black and felt better about buying the HKS set. I am going to have to recommend you buy 5 though. After several hours of installing the plugs one of them was bad and it didn’t run right. I had to put an oem plug back in until the replacement arrived.
