Public Service Announcement: Si Fuel Injectors

[Design]

A heads up to fellow Si owners that the DI fuel injectors are on nationwide backorder. Long story short, Honda discontinued the part and is updating with a revised injector, due to high failure rates. The revised part has been on nationwide backorder for about a month.


If you encounter a misfire or cylinder rich condition, be advised that your only option is to wait things out, scour the junkyard, or source a reman unit (if you can find one). I’ll update this thread once my own order has been fulfilled.

Carry on…


EDIT: Received feedback that the head gasket may also be on backorder. If anyone is able to fulfill an order on either part, post here and I'll update the OP.

EDIT 2: The revised injector has been released and is slowly making its way back into circulation. For now, this is a dealer-only item with a 4-8 week wait time.

OR…….

Ask this guy if he will sell his. I have 2 full sets !
Bidding starts at $10,000 per set.

But seriously…. Mine are lightly used and I could sell them if anyone is interested.

Also head gasket kits are apparently on backorder as well.

What about any aftermarket injectors.

I believe there aren't any on the market for 10th gen Si's

What about those hondata ones?

There's always this option. A 3 week delivery time (from Japan). No bargain though.

Thanks, and yeah those are the old ones. The new kit is reportedly sold with the fuel joint pipe as a single unit. Around $600 at the dealer and $400 online (once back in stock).

$2600

Not sure which injectors they use exactly, but u would need the adapter they provide in the kit. Entire kit is $2600

I wonder how the new part will hold up. I’m sure Honda revised it for the long run

I can sell a set with 3,000 miles on them for $200.
The other set have 30,000 and I can do for $150.
Just saying……options

Injectors typically last 200K+. But Honda has struggled to partner with a reputable supplier for their DI configurations. This will likely be the third injector set to get a TSB and/or warranty extension in the last 5 years. And I believe all of them can be traced back to Keihin.

My last Mazda was DI and went 200K on the factory injectors (Denso, IIRC) before I sold it .

Thanks, messaged you.

First time being back on the forums in a while - are there major issues with the Si Injectors? How would I keep track of the misfires/cylinder conditions? KCon or a PCode?

 

[icemansi]

Id imagine Honda taking the L and issuing a warranty extension
