If you have a non egr intake you won't even need to block the port.
A 70 on a stock intake will do nothing but lighten your wallet. The stock opening is 60 mm I beleive
I with you on that one. It's a sure way to introduce problems by picking up warm, turbulent air from inside the engine compartment. That will definitely mess up the airflow through the MAF and cause air/fuel mixture problems. It will go away when you have the stock airbox back in place and all the ductwork connected up properly.You didn't run it open like that did you?

Also try rotating the maf slightly. For some reason sometimes that seems to make a difference.
Anyway, the sanding paddle left a nice finish and removes material well. With my other already mods and the new bigger MAF, tb egr it ripped up the tires easier at low rpm and felt like it opened up the top end. SOTP feel was really worth it.To port the intake, I used a maother thanpening surface, used the 70mm gasket as the pattern, and marked the circle from the bolted gasket. I took off the gasket and two tools. 1. A mini air grinder with a carbide tip and 2. A sanding flap wheel from the woodworking section. The sanding paddle wheel would have been enough on a narrow drill to open the opening and actually go down the throat to get the bolt posts. I used a long pair of calipers to make sure I did not get too thin on the upper intake bolts. More to follow.
Opening up the top end for little cash is the plan. High five!70mm '94 Marquis MAF in place installed straight up with adapter and all tubing. Its working well. I trimmed a small amount of tubing lip where it hooks to the factory air box to extend the tubing and oeliminate a small kink caused by the slightly longer assembly.
I notice the engine no longer falls flat at 4500rpm like it did before. It pulls well slightly beyond 5k now. I'm told the skinny snout for the factory airbox on the inner fender is another restriction so I suppose I'll either modify or remove that part (keep the factory box though). I have a K&N element in the factory box.
The Marquis MAF cost me $25 at a local pick and pull yard.
