Insulating IACV Gasket
I gotta rewrite this thread cuz theres so much to add...
So this is still in the prototyping stage and they are made by hand but they are made with accuracy. 1/8" teflon, they are durable, soft, and resistant to heat up to 575˚F (300˚C). No only that but it is a great insulator. I use these on my car so Im practicing what Im preaching.
Teflon has a thermal conductivity of .25 W/m K (watts per kelvin per meter) whereas aluminum has a conductivity of 237 and iron of 82- huge difference in thermal conductivity
Hondata and Skunk use teflon for their thermal gaskets. They charge a lot more too.
The Concept:
Many people try to keep the coolant from flowing through the intake manifold. A common mod includes installing both a throttle body gasket and an intake manifold gasket. But there is still the coolant running through the IACV. I see people bypassing their coolant lines from the intake, this messes up your idle and even performance. But the IACV and FITV gaskets will insulate those areas. This can also be used in conjunction with or in place of the F23/Euro manifold swap on the f22s where a 3 to 2 wire IACV conversion plate is needed. Please let me know if you would like a Euro 2-3 wire adapter plate made from teflon.
Im looking for people to try these out and give me feedback. The IACV gaskets are just for F22 and F23 IAC valves since I do not have a template for other IACVs yet. If you know of any other engines that have the same size let me know. I can make custom ones if you send me the dimensions.

none that I know of. Plate itself costs $40+shipping. Im working on making one from teflon to sell.
*NEW*
3/8" Prices
• Idle Air Control Valve Gasket 3/8” - $10 (Available for f22 and f23 IM)
• Throttle Body Gasket 3/8” - $30 (Available for most throttle bodies I can do one to fit a normal IACV or the conversion plate)
• Low Manifold Gasket 3/8” - $55 (Available for any Engine)
• Fast Idle Thermal Valve 3/8” - $10 (Available for most Honda TB’s)
• Upper Manifold Gasket 3/8” - $45 (Available for most Engines with separate plenum and manifold)
10% off if you buy a kit of 5 or more gaskets
Items are subject to material availability
Thicker sizes are available for higher price. 1/8" is the thickest you can get using the stock head bolts. Any thicker you will need new bolts and it may mess up your injector timing spacing them farther back. I am also working on getting the material for a Throttle body spacer made entirely of Teflon. See the update below. This is less expensive than other competitors and theirs are made from metal. This will provide a large amount of insulation. Extended bolts are included.
Throttle body spacers basically increase your plenum and provide an increase in low end torque.
Update:
I did a price on materials.
I can make a 1" thick throttle body spacer/gasket with the extended bolts for $40.
The cheapest TB spacer you can find is from OBX for $55. And thats aluminum.
Keep in mind these are done by hand and are still in the prototype stage. If theres enough interest Ill bump up to a machined product. Once I do, I will send any customer of the prototype a new, machined product at 50% off if above $10 Nonetheless, the items serve their purpose and arent gonna be seen once installed anyway :P
Im bracing myself but I hope you guys take this idea tactfully, honest but friendly feedback please.
Please allow for 4-14 business days for orders to arrive.
This is being shipping from Syracuse, NY 13204. Quick shipping through USPS
Why not give it a try? They're inexpensive and no one else makes custom thermal gaskets for so cheap.

Update:
Installed it on my car and it does great. The difference between the IACV and the intake manifold next to it is noticeable to the touch. About 30 degrees up to temp. The seal is perfect. No vacuum leaks, not idle hesitation or rough rpms.

First sale on another forum.
Some more to add:
Results were anywhere from a 30 to a 50 degree difference in temp. Keep in mind there is still heat sync from the engine head since I havent put my lower IM in yet but I kept the laser pointed as close to the IACV as possible.
Heres the video link, sorry you gotta tilt your head to see the readings.

This is the car warming up. On the IAC valve

This is on the IM right after the gasket
