Lets talk sq**rt, shoot, dribble, leak and incontinence.
Acura RDX Injectors, a popular upgrade injector when more fuel is needed. They are a convenient drop-in upgrade to many cars and flow 410cc/min.
Honda B series injectors - 240cc/min
Honda K series non Type R injectors - 270cc/min
Honda K series Type R injectors - 310cc/min
Anyway, we have been selling and using these since 2007. Many of our customers would have experienced these first hand.
In recent years however, with the advent of online shopping and many fakes available, how do we distinguish between the genuine parts Made by Honda (Denso) and the fakes. Without buying one and having both side by side, you will not know. But 1 of the big tell tale sign is when the advertisement mentions the word OEM; be extra wary when you see that.
So what's wrong with using fake injectors, let's list down just a few possible scenarios from poorly constructed injectors.
1. They may be unable to keep up with fuel pressure and leak.
- inconsistent fueling
- extra fuel sq**rted even after engine is shut down due to fuel pressure (and causing poor hot/warm/cold restarts)
2. Not flow what they say it flows.
- I have personally tested a batch of 100 pcs of these fake RDX injectors on my injector tester. They ranged from 370cc/min to 600cc/min. Good luck if you get 4 pcs from both ends of the spectrum.
3. Injector tips breaking off
- Any foreign object getting into the combustion chamber is unwelcome...
There are a whole host of other reasons... but basically just use original parts (and ensure the shop that sells it to you does not sell you any fakes).
The original one should come in a Khaki colored box with the Honda part number 16450-RWC-A01.
If buying online, get it from a Acura dealership/website and not any other portal. They should be about US$70 per pc, still reasonably cheap for a set of good injectors.
But if you still insist on paying US$45 for 4 pieces of injectors from dubious sources, please inform your tuner truthfully what injectors they are and it's source.
