Bosch Gen III (EV6) injectors for S14 engines
Hi All,
Following on from THIS
Well, we're a month down the line from when I fitted the new injectors, and they're brilliant ! In most respects you wouldn't know that anything was different about the fuel system; and certainly not that the modification was in any way experimental. The car behaves exactly as you'd expect: You turn the key, and it starts from cold, but the consistency of the idle is better, and I think I'm getting a slight improvement in fuel economy; but I'll confirm that in another couple of weeks.
Where I do notice a difference however, is in the performance. Something I used to notice with my 320is, but that I also noticed with my 318is is that on most days, the performance was OK, but not exceptional. Then on some days, for no apparent reason, irrespective of weather, air temperature etc., the car would perform noticeably better - noticeably more willing to accelerate, and begging (much more than usual) to be driven quickly. Since I've fitted these modern injectors, that extra sparkle is always there - consistently. The performance is much more willing, the throttle response is better, and the engine doesn't get "bogged down" at low speed - you're never left waiting for the power when trying to pull out of a junction on to a busy road with a lorry breathing down your neck !
So far these EV6 injectors are a complete triumph - a total success. So much so that if I were using factory standard injectors (particularly in a OE spec engine), I wouldn't even think of sticking with them - I'd use the cross reference chart mentioned in my first post (and no other reference chart), spend some time selecting an equivalent EV6 injector, and replace the old injectors as a matter of course.
The fact of the matter is that you'll spend as much money having the old injectors cleaned than you will buying replacement EV6 injectors (0 280 155 715), and after having spent the money, you'll still have a set of 25+ year old injectors in your engine; and modern injectors are just better - full stop.
Best Regards,
Dave.
