If anybody is interested in making their own intake manifold spacer, you can do it with a spare OEM upper manifold.
Parts needed:
- spare upper intake manifold
- 6 extended manifold mounting screws and washer (I'll update with actual size)
- new manifold gasket
- pair of balls to cut the manifold
Process:
- simply machine/remove the intake runners from the mounting flange on the manifold.
- make the top of your cut on the spacer perfectly flat (this is the top of your spacer, must be smooth and flat for the gasket to seal)
- install between lower manifold and upper manifold using new extended hardware
I like these a lot better than aluminum spacers for a number of reasons:
- lighter weight
- less heat transfer
- OEM quality material
- full 1" thick (which is double the effective thickness and theoretical improvement vs currently available 1/2" aluminum spacer)
I've done this and tested it thousands of miles, on and off road in a prerunner (real prerunning desert race courses and large whoops at high speed) with zero problems. Zero leaks or damages.
It's really hard to get this across to people on Tacomaworld, because they're all convinced that this is a BS mod and most of them are too chicken shit to do anything that doesn't come with a factory warranty. I'm pretty sure XR owners are more handy and aware of the actual benefits of a manifold spacer.
I don't make these to sell, just passing on the info for those who are equipped to make their own.
Pictures should be pretty self explanatory. If anybody is in the Socal LA / OC area, you are welcome to check mine out since I no longer need it. I also have a good spare manifold if anybody local needs one.
Pictures before install / testing:
After testing, still perfect. No leaks or damages.
Installed. Fits better than a glove:
