Does t clear the seat and sides? I know mine didnt have a chance but i had the rad4 spacer too

[MacDaddy_rxpx]

Yes it does clear. I milled quite a bit off of the manifold so the tip of the heat sync catches the exhaust flow.

Is it vital to use the heat sink with the o2 sensor? There are people using it without the heatsink yer?

I dont use a heatsink. No problems and I leave it installed. Runs with the ski.

This would help the sensor have a longer life span but it's not "Vital" Like your reading is going to be off or not work.

That's a nice piece, you going to make any more of them?

Surely you had to hit the water jacket. I know its a critical drill. And most wont use a older manifold because it doesnt have the raised surface to drill and tap. Looks like you ground the bump out right off.

Personaly I think its completely unnecessary.

I use the heat sink on all my turbo/supercharged cars. Just playing it safe. By milling it down, the sensor depth is correct giving us a proper reading.

I run a heat sink. I leave sensor in and it has not gone out in header.
Not sure it helps but is cheap and if it does keep it from fouling it is worth it.
The Big difference in life of the sensor seems to be having it in manifold and not j pipe.

I pull my EGT readings from same spot.

I think its moisture in the J pipe that kills sensors
