Denso is one of the brands that OEMs use quite often and are quite good. European OEMs use Denso and Bosch. 6 of one, half a dozen of the other. You could upgrade coil(s). You could change the air filter for a high flow one. Plug gap is spec'd at.029-.031 inch. You can increase it to.032-.033, which will create a hotter spark, but also put more load on the coils.
