I thought about wheel covers, but these are 16" rims. ID of the rim is about 17" Any good threads on covers this big?
Yes, the air going into the grille tumbles around the engine bay and causes all kinds of ruckus; the same is true of air going underneath the van, hence the air dam suggestion. Headlight covers, you might say, are the high-hanging fruit.

We have lots of threads on grille blocks and air dams for large vehicles, so search around and you'll have plenty of reference material!
