Hope, this has not been asked or answered. How do I safely remove the EGR spacer from the Phlenum? I've soaked the four bolts on the spacer for two days and they will not turn. Used the method suggested by Matt on the Youtube Vid.

Also, whats the stock size for the EGR Spacer?

Yeah, they're a pain! The steel studs tend to corrode into the aluminum on the spacer and the manifold. My go to is PB Blaster but Kroil works great too. Spray the penetrant, tap on the studs with a ball peen hammer, several times. Soak and tap over and over. Bang on the EGR spacer with a dead blow hammer. Try to tap in a thin putty knife between the spacer and manifold to break the seal. Nothing fun about it. Patience is the key here! When you do get it off, clean it well and definitely replace the studs with a new set.

I have a stock throttle body, will those studs fit or should I upgrade to the next size spacer n throttle body! From what I was told Stock is 58mm n should go to 65mm. My intention are to keep the car stock as possible. I live in Kaliforniski n they r strict on Emmisions.

Leave it stock, no point when:
You're in a Communist state so strict emissions.
Stock heads and intake will only move so much air, spend the money on a K&N or similar air filter in the stock air box and swipe in a rear gear like a 3.55 or 3.73.
I would slide a better header in but that's kinda splitting hairs when bone stock
Oh, and this is JMO and should not be used as mechanical advice.

For a used ond get on www.car-parts.com and search for an "air flow meter". Saw some on there for around $30. LMR sells new ones here:
