Genuine Subaru 16546AA16A Engine Air Filter
Sluggish acceleration or fuel economy slipping? A loaded air filter starves the engine of clean air and can contaminate the MAF sensor. The genuine Subaru panel element restores factory airflow and seals exactly in the airbox — no gaps, no bypass dust.
About the label: Subaru superseded part 16546AA150 to 16546AA16A. Your filter may arrive in packaging labeled 16546AA150 — it is the same filter under the previous part number.

FAQ
The box says 16546AA150 — did I get the wrong part?
No. 16546AA150 is the previous Subaru part number for this exact filter; Subaru superseded it to 16546AA16A. Same element, same fitment.
Will it fit my 2016 Impreza or 2018 WRX?
No — this filter is for the 2017+ platforms (and WRX only from 2022). Earlier models use a different element.
How often should I replace it?
Around every 30,000 miles under normal driving; check it sooner if you drive on dusty roads.
Is installation difficult?
No — unclip the airbox lid, swap the panel element, close the lid. A couple of minutes, no tools.
