Use the PVC, but don't bypass the maf sensor. If you do it will run like dirt. This sensor lets the engine know it is getting enough air. I changed the air filter on my 1985 318i recently and did not completely reattach the maf to the throttle body. It would hardly start, let alone it ran like crap. Just pipe the cone into the maf w/pvc and you still need a heat shield.
And how 'bout a pic?
