M20 Silicone Air Intake Boots

The later manual e30s used a single check valve. I believe I started in 90. I like to tap the bottom vacuum port for the blow off valve.

Do you have a pic of this? I thought of running a diverter valve in there too!

Got an email from the manufacturer

"Hey Nigel, Your hoses will be ready by the end of the month. Estimated by the 31st"

I seriously can't wait to get mine. My old stock boot is all cracked and leaking.

No. I was trying to make one with a 3" opening but i could not get a consensus on the length or shape of the boot.

What do u need from me to make this happen? Want me to send u a boot? I think its the same as length as the stock one.

No list needed. Just click on my website and pre-order. I'll change the prices as soon as they ship them out to me.

I have purchased one of these intake boots and it has held up just fine over the last year and a half. I had the dual brake booster ports on the TB, capped the lower one off (just to ensure any oily sludge from the PCV doesnt through the line on the lower port) and ran a single line with an E21 check valve to the booster. There is absolutely no change in brake assist from what I can tell and it removes the costly stock check valve (E21 valve was $12 or less) and simplifies the vacuum system just slightly.

So I am SOL?

[einstein57]

It was replaced with this boot for safety concerns.

That was just the prototype for the previous design. It has been killed with fire.

That is a terrible shame! No fancy silicone intake boot for me :(

Would this fit an 01/88? When compared to the stock photo for an up to 10/88 the design seems similar:
