So I picked up a set of NA8 injectors and realized one of them is a bit off. The color is slightly off from tan, there are no markings on the side such as Denso or the part # (195500-2180). Rather it has etchings on the top; 8325 and RIN-570X?.

Is this odd injector a 1.8 in diguise?

 

If you like, send them to me and Ill clean and flow them install new filters and send them back. $5 a piece.

You will know what you have and peace of mind.

 

Thanks, I'll keep your services in mind. I don't plan to keep these injectors for too long. My next steps are MS and larger injectors. Should I aquire used injectors, I'll be sure to PM you. Do you have any references?

In regards to my original post, I assume the odd injector is from a 1.8 but with a different appearance?

 

Probably a replacement injector a dealer swapped into the original car at some point.

 

Interesting replacement....

Any of these?

It is an interesting replacement. Ive searched all over for a match but couldnt find any. It was working fine on the car it was pulled from, heck it was even boosted.
