At 30,000 changed air filters

The cabin air filter looked dirtier than the engine air filter but holding the engine dirty filter next to the new one up to the light you could see a big difference. I used the Wix 24103 Cabin and the Wix 49247 Engine Filter and they both fit well in my early 2013 GT and looked identical to the stock with the same number of folds & thickness etc. Rock Auto .com bill was $36.

I used the Mazda air filter and changed them at 19,500 miles and the first thing I noticed was the improved acceleration. Seems like tall the salt from the roads really clogged up that air filter.
