All I can say about the upgrade is that it's been some while since my motor idled and revved as smoothly...example:- prior to fitting the new injectors, the motor had a "hiccup" whilst idling...every so often it would do a "blat" instead of continuing to tick over smoothly...I was told about sticky valve lifters being the cause etc etc.. and having used engine flush, injector cleaners etc to try to remedy the issue...without success...this has cured the hiccup, and the power delivery is fantastic...it feels as if the motor is more responsive throught he rev range and it seems to arrive at the redline considerably quicker...all in all a very worthwhile upgrade from the OEM 2 hole injectors..added to which, these are unclogged / tarnished etc and deliver the fuel at 100% efficiency...
Here they are going in....
