Super fast shipping, got it in two days! The packaging looked a little rough, but the filter was in perfect condition. I called support with a question and they were super friendly and helpful.

Arrived quicker than I expected, which is always a plus. The box was a bit dented, but the filter was in great shape. Had a quick question and the support team answered it fast. Great experience.
FAQS
Yes. PHILTOP’s high-flow design reduces air restriction, allowing your engine to breathe better. You may notice improved throttle response and a slight boost in power.
No. An engine air filter protects the engine intake. Cabin odors are generally handled by the cabin air filter.
A severely restricted or incorrectly installed filter may affect airflow, but a warning light can have many causes. Professional diagnosis may be needed.
