I beleive no one has seen this plenum, it's a myth.

Personally I reckon it's a photoshop job.

good photo shop job

Why does it have 2 fuel rails and 2 sets of injectors

from what I can gather u add a map into the ecu to add more fuel by the extra fuel rail at high rpm to get an even afr across all cylinders.....

could be wrong though.

"Best of all, the APS plenum also has provision for an additional 6 injectors in order to supply the precise amount of fuel at extreme engine power levels. By utilizing additional fuel injectors, optimum sized main injectors are utilized in order to deliver excellent throttle response and fuel economy under normal driving conditions - but at full throttle and high power, the additional injectors are available to supply additional fuel. This approach is far superior to very large individual injectors that perform poorly at low flow rates (low duty cycle) and result in high fuel consumption and lacklustre throttle response. The APS plenum is designed to accept the standard XR6T injectors in order to deliver the most cost effective solution for the XR6T performance enthusiast and you can now enjoy the best of both worlds - excellent throttle response and frugal fuel economy under normal driving conditions along with precise fuel delivery through the additional injectors at insane horsepower levels - all in a very cost effective package!"

I could have jus done that I guess.

So it is availabe? Any idea of cost.

As far as I know there was only ever 1 or 2 of these units in existence. They never went into production past the test units.

There are units available now that would be as good if not better than this unit. The additional fuel rail would make tuning considerably more complicated and expensive to get right.

I wouldnt be counting on ever seeing one of these. But give APS a call and let us all know what they say!

I went for a drive in that silver APS XR6 a few years ago. It went 307kph at Avalon LOL. It had this plenum on it, so yeah it's real. It was pretty quick too!
