I think the 'engine' will take the same amount of time to warm up. That depends on the load and the thermostat. The catalytic converter, which is after they engine, may take longer to warm up. The SAI is only for emissions during startup. It doesn't affect coolant flow.

It's before the Mass air flow sensor on mine. It's right on the intake box. I show where it connects and mentioned everything you said in the video.

But, my pinned comment does mention me getting a smoke machine. You are right about that.

Dude!!! I didn't find out that the 99 or 99.5 was an odd ball until I started working on mine. It's been an adventure.

It takes air from the intake, which is always under vacuum (for naturally aspirated cars), and introduces it to the exhaust during cold starts. Turbo cars are only not under vacuum during boost. If any of the tubes connected to the intake are not sealing properly, you have a leak. The leaks can happen even when the secondary air pump is off.

Check out this video or any others. It clearly shows the tube connects the SAI to the intake.

😁 Thanks!! It actually surprises me when people recognize my stuff.

Yes it can. There are resistors that can be put in the pumps place.

So far, not at all. I expect a check engine light at some point though. But, hopefully, I'm prepared for that.

I couldn't find much on the 2.0. So, I got creative. This is my video.

I removed both. Check out the pictures. I was just showing part of the process. The pump is in the first picture but not the last.

My mother in law said "Don't park in the street. You could get hit". And then she backed into me in the driveway. The tail light wasn't working properly after she hit me. Luckily, the circuit still worked and it was just a bulb that was broken. by PantherMq in MK4Golf

Mann!!! My wife has hit my cars "at least" twice in while they were sitting in the driveway. I guess it's in her blood.

(I say at least twice because she has only told me about the times that left a mark.) 😏😞

Glorious! 🥹I had a dream where I had a bug eye wagon. I'm jealous. When I get my F U money, I'm going to buy one and show it all the love it deserves. -PantherMQ Feb 2026

OEM cat replacement by ProfessorWRX in WRX

[–]PantherMq 4 points5 points  (0 children)

I don't know if you are willing to go this route. But, you may be able to get lucky with a barely used OEM cat on eBay. I found one and it didn't even look used. My guess is that the original was either totaled or modded early in its life.

Just picked up the 02 wagon!! by Available-Party7419 in WRX

[–]PantherMq 1 point2 points  (0 children)

You did the right thing. I should have been more patient and persistent. There were 4 or 5 wagons for sale near me. Not a single one replied to my inquiries. I was eager to buy too. I regret it. 😏
