Chloe C. ★★★★★

After struggling with a dirty filter for months, this replacement dropped right onto my velocity stack with zero hassle. The 6-inch opening matches perfectly, and I'm glad I went with the official replacement instead of a generic.

Jason ★★★★★

The 6-inch opening fit perfectly onto my velocity stack without any hassle, so installation took just a couple minutes. After putting it on, the intake seems to breathe noticeably better than the old clogged filter I was running before. Exactly what my Si needed for a quick refresh.

Isabella ★★★★★

The 6-inch opening fit perfectly onto my existing velocity stack without any modifications needed. The filter itself seems well-constructed and sealed tightly against the intake tube. My Civic Si's air flow feels consistent after the swap.
