I'm really thinking about pulling the trigger on this and trying it on my 1NZ-FXE.. Should bolt right up.

If your intake manifold looks like this...



I have no idea as to the spacer's effect on your engine...

However, it would be an interesting experiment because you have an Atkinson cycle engine and not an Otto. You'd also need at least 3 inches of free space in front of the intake manifold for the spacer to fit. From the drastically shallow design of that manifold it looks like free space might be at a premium. But I don't know your under the hood situation. Can you post a pic of the space in front of your intake manifold? Then you can go from there. Don't get one without first finding out if it would even fit.

Hey wait a minute... that intake doesn't look stock. Did you make a custom CAI for it?

There's an experiment you can try...
Unbolt the 5 bolts holding the intake manifold, yank all the hoses and put them out of the way, and then measure how far away from the head you can pull the manifold before anything hits the plastic reservoir of anything else in front of the engine. That will let you know whether or not a spacer will work. To me it looks tight in there, but it's hard to tell from pics. You'd know better than anyone else because you're right there.

DOOOO EEEET! Dyno runs or it didn't happen!

The only issue I can see is that very strange 1-2-4 (opposite of a 4-2-1 tri y exhaust manifold) intake manifold is specifically designed for an Atkinson cycle engine and is tuned for a very specific optimal rpm range. So an intake manifold spacer lengthening those extremely short intake runners is likely to push the curve outside that range. While there's a chance it might make it better, there's a greater chance of making it worse.
