I have had a set of ID1000 on OEM fuel rails for a while.. Since the vendor says it was 'true drop in' I though it was pretty straight forward so it was installed by a mechanic last year..and last week I took my injectors out just to service them. Guess what I found out?
See my picture..
Since the ID1000 are 41mm from the tip to the slit where the metal clips lock on to.. once you have the metal clips on locked to the rails..this has basically shortened the injectors by 2mm (+- 0.5mm from movement) from the fuel rails to the tips.
The depth of the injector seat in the engine head is approx 7mm so 2mm (+-0.5mm) off is maximum of 35% off which is quite a lot
What this does is that the injectors sits very shallow in the engine head and cannot be adjusted to seat properly due to OEM fuel rails not being height adjustable. By sitting shallow in the engine head, it becomes risky to fuel leaks, moreover the fuel spray pattern is compromised. For a perfectionist like me.. this is unacceptable.. I dont not understand why they state them as 'true drop in'? What are others tuners doing to the ID1000 during installation?
What I have done to resolve this?
Please see the ID1000 picture.
I have used a hand saw to cut a circular slit on the 43mm mark.. this has basically allowed the metal locking clips to lock the ID1000 to the rails at the correct OEM specification.. therefore allowing the injectors to be seated properly into the engine head. Once installed..the injectors sits perfectly tight and ALL the way in leaving NO gaps between the engine head and the injectors..engine now starts within 1 sec of pressing the start button.. both hot cold..
I am sorry I have not taken any photos of the finished modification but it now gives me peace of mind and performs perfectly
I urge all ID1000 on OEM fuel rails users to double check their installation.. Also I dont recommend grinding OEM rail mounting holes as this height adjustment technique affects the alignment of the injectors and its seating (not vertical)
>> No offense to Tony, in fact Tony has been very helpful with my queries..but these are just my findings on these 'true drop in' injectors
EDIT - changed Title from 'aftermarket injectors' to 'ID1000 injectors'
