Hello everyone! Thank you so much for having me here. Im new here and just wanted to get some info on injectors for my 1995 q45.

Which injectors do you guys recommend. Im not concerned about the price as much as i am about quality. Which ones are the best i could get for my q45? Because ive seen black ones.red ones.blue ones.purple ones...so im kinda confused about it . if anyone could help i would be eternally grateful👍✊🙏🙏🙏- Ivan

Ivan,
I've been using STANDARD MOTOR PRODUCTS FJ284 for over 5 years on my 94.
Some advice:
1. Injectors can't be rebuilt, don't bother.
2. while you're at it, replace knock sensors and knock sensor wiring harness. You might find a good deal on genuine Nissan on ebay.
3. Replace all fuel line with Nissan fuel line and injection hose clamps (see other threads)
4. Good time to replace spark plugs and valve cover gaskets.
5. Check the under plenum hoses, see discussion thread on this topic.

The current Nissan part number for replacement is 16600-67u10. they have a purple top. Whatever you get, don't forget that there are 2 o-rings for each injector--those p/n are 16618-53j00 and 16618-10v05.
agree with other points from dnudelman.
My '95 still has all 8 factory tan tops at 1528xx miles.
The '94 has all 8 -67u10 replacements. 3 of those were done at infiniti just before I bought it, I replaced the other 5 pre-emptively 12 years ago, so those are at about 50k miles all on E10, no issues.

Oh, as a hint, check rail assemblies with new injectors before installing. One of the cleaning vendors here I trusted did not and destroyed my engine.

I recommend fuel injection cleaning by:

Mr Injector / Bill Johnson
6280 North Government Way Unit 4
Dalton Gardens Idaho 83815
208-762-3450

They do pressure test the rail assembly after the clean injectors are mounted.
