I have barely used Denso 540cc PNP Injectors for your Miata build. 13.8 ohm. Previous owner put approximately 5k on these before selling these to me. He bought them new. When I was taking pics to sell them I noticed a small crack in the top of one that will probably have zero effect on performance but it gets them discounted none-the-less so I'm losing my shirt. $150 for the set. New were over $300. Pics:

know what type of spray pattern they have?

 

Does this pic answer your question, Tech?

 

no, but still nice to see.

 

Any insight on how to find the answer? I was told when I bought these that they were RX8 injectors.

 

Okay, Tech...best I've found is this:

It's an Ebay ad for same part number Denso injectors & says spray pattern is "Cone (4 hole)" if that helps.

 

I'm pretty sure those are RX8's. I mean, look at the old RX'7's, they make em in 460cc, and 550cc; so why not make RX8's in 425cc and 540cc? The old RX7's are pintle type, while the RX8's are bosch disc type just like a factory miata injector....well at least like my '99 factory miata injectors. They are the same in size too, so they should be a 100% PNP injector.

 

They are 100% PNP.

 

Well, $150 obo.

 

Buy some awesome injectors & have a Fresca!

 

Can you circle the cracks in the picture? I can't see them.

 

Well, I told you they were so miniscule that they can barely be seen. They are also on the little collar above the top O-ring so I really don't think they will even matter at all since some PNP injectors don't even have a plastic collar before the O-ring. So, enjoy my awesome photo editing.



P.S. Now that I look @ it, there appears to be one @ almost 12 o'clock that didn't get circled.
