Well.... I picked up the modified air cleaner lid from the machine shop with the 2010-11 Chevy Malibu V6 K&N air filter in it. I also did some mods to the base to lower it and fit a 2.25" tall S&B filter in it. That replace the 1 3/4" tall K&N.
I took it for a test drive today and SOTP says it's definitely quicker. Both sets of vacuum secondaries snap open much sooner and much quicker. The Dyno will tell the though...
Here's the old setup...
Here's the modified base, it allowed for almost 1/4" drop.
Here's the new lid with the embedded filter.
Here's the bottom of the filter lid.
The finished product.
Good or bad, I'll post the results of the dyno session.
