Super easy and inexpensive
Size: (Pack of 1)
It was super easy to swap out myself! I just searched “how to change engine air filter 2017 Acura RDX” on YouTube and watched the first video that popped up. It took me longer to type this than it did to change the filter. Plus, this one cost about a third of what Valvoline was going to charge me to replace it.
