This is a standard replacement air filter for your RX-8’s air filter box
OE spec this item should be replaced every 3 years according to the Mazda Service plan.
Why not look at our K&N Filter as a possible alternative.
You may also need to change this if you have overfilled your oil and it has contaminated your original air filter
This drop in in air filter from K&N is designed to last the lifetime of your car.
It will never need replacing, unlike the standard air intake filters, and will only need washing and re-oiling (every 50’000miles maximum). For what is roughly double the price of a normal Air filter you can get better air flow and a reusable filter.
The other upside to this is that if your unlucky enough to overfill your oil (on early cars) it would have been blown up in to your intake and contaminate your air filter with oil, Possibly leading to some of the following symptoms:
An excellent addition to any service plan. Ask about the K&N panel filter when you book your next service
