I'm starting a review thread. I'll be installing this sometime in the next couple weeks. I'll also be installing the newer style Bosch 3 fuel injectors out of a crown vic.

here's the spacer, TFS-51520004 , a cotton canvas phenolic 15"x4" board worth about $20 in uncut form. It's not the best material for a spacer, but it is strong and is still considered a great thermal barrier.

anyone else running one?

I'm pretty sure Aussie rod knows something about em.

I'm running one on my brother's Aussie Falcon with the Explorer upper/lower (mainly to clear the valve covers we are using, as the upper is reversed for our application) and I'm amazed at the difference in the heat soak it prevents to the upper half. At a recent track day, the IR temp gun said 98C on the lower and 48C on the upper. Considering the amount of heat under the hood and I was FLOGGING this car around the track, that's a pretty good indication to me that it can work.

I run one. BTW, I have a Box-R upper for sale cheap. New never used. PM if you can use it.

I am curious about this. Is it supposed to give you power via the cooler denser charge or just keep the under hood temps down?

More dense air charge to my knowledge. It's supposed to lessen the transferred heat to the plenum.

Also using a spacer vs not using one makes the intake path longer which lowers the optimal rpm range of the intake.

Seems like a minimal cost upgrade. Is it a noticible gain?

Bringing the torque curve lower in the rpm range?

Yes, in general (vs no spacer).

started on this tonight. I about shit myself when I was playing with the butterfly valves, I was opening them up and they would fling around. They were loose! at full throttle they would close half way O.O luckily all 4 screws holding them on were still there. I guess this is why I would loose power past 3000 rpm

There's 6 bolts that hold the upper plenum on and the middle one underneath is a T-50 Torx that you supposedly have to get to with a 1/4 bit, which I don't have so I'm waiting on parts. Couldn't get to it with a T50 3/8 socket and breaker bar, my lowest profile option...

Keep us posted I'm very interested in if this spacer helps. Glad you found those loose screws before one got digested!

few new things..
first if you look at the screws holding the throttle valves on, the tips are oblonged to prevent them from backing out all the way. Thank god lol

second, the center bolt is a T40 !! not a T50 like I read in 2 other posts... they don't even make a 1/4 T50 unless you use a long T handle, but that doesn't matter now because it's a T40 !!! garrrrr

I've got the crown victoria injectors installed and pulled the valve covers to be cleaned and new gaskets. I'll also be replacing the EGR pipe, PCV valve and a couple coolant hoses behind the block while i have easy access.

Why crown Vic injectors? More power? Are they larger or something?

newer injector design. same fuel output. they spray from 4 small holes rather than 1 large. smoother idle, more reliable, maybe .25 more mpg? lol

Lol one can only hope!

The better spray pattern should give you more power all the way around.

I'm liking the sound of that.

part # for the Crown vic injectors?

I went with this combo because it was the cheapest option at the time

19# EV6 injectors for my 302

Then you need to buy the EV1 to EV6 adapters (not to be confused with EV6 to EV1)

There is injectors out there that are the original bulky design that have both a 3 hole and 4 hole design, this way you wouldn't have to buy adapters. But prices and be expensive or cheap. I have 1 that I will get the part number for here soon, that way I can tell you guys what cars they come on in the junkyard, if any.
