Just bought a cabin air filter, WIX 24777, from Fleetfilter.com for $16.73. It's good for SRT6 and all models. They also have our oil filter, WIX 57078 for $9.69 each. It's a reboxed Mann Filter and fleece as well. They have discounts for $50 and $125 orders and shipping was reasonable. I bought a cabin filter and 4 oil filters and it came to $11.08 for each oil filter, and $18.12 for the air filter, shipping included. No tax unless you're in Texas.

I'll update when it arrives and I install it!
