NEED HELP ASAP - Do RDX Injectors Fit?

[Neemerz]

hey everyone, quick question, do the rdx injectors fit the 9th gen stock manifold

I do not believe they fit. The rdx injectors will fit the rbc manifold. I'm 99% sure the rdx ones are a larger diameter.

could be wrong on "diameter".... I can't find a pic of them next to the 9th gen injectors....

compared to the rsx which used a k20 engine....

Rdx are actually smaller in diameter, and will fit the RBC. They can easily fit our manifold if you get slightly larger o-rings.
Exact size info on the o-rings, i do not know, but @VitViper should know
