Twin Hole Vs Single Hole Injectors

[J_Red33]

Naah sorry mate. They're denso just like all other Mazda stuff & what carl says about them is quite true. A cheap high flow injector, not necessarily a good one.

It's also important how injectors flow at low duty cycles (ie how they flow when using minimal fuel at idle or cruising) You will have a lot more trouble getting your car to idle nicely if the flow for short on times varys quite a lot.

Cleaning them does help for sure, most injectors genrally pull up better after a deacent clean, though certain types like later model Jecs injectors the difference was barely nocticable cos they were so good in the first place!

It also depends on exactly what model injectors you are running. I'm digging more of this out of my head each time I read this & I do remember testing a handfull of newer type rx-7 ones that were a lot better, but not outstanding.
