    Was at doubt at first with the sparkplugs on the other page, but the seller responded to my question and provided me the correct sparkplugs for my car, delivery was a day ahead of the estimated time frame. Fitted and liked it, the throttle response has improved compared to the old one, and the price is way cheaper compared to the "oem" from the dealership. Fuel consumption wise, i'm not sure if it gonna improve, since I'm kinda heavy footed on the throttle.
