When it comes to servicing one’s own car, the air filter is normally just about the easiest thing to change. Despite this, it’s often overlooked by lazy owners. Having a clogged air filter can increase fuel consumption and reduce power: it really makes sense to change it regularly. Fortunately, changing my Mazda MX-5 1.8i Merlot’s (also known as Mazda Miata in the U.S.A., and the Eunos Roadster in Japan) air filter was extremely straightforward.
My Veloce Mazda MX-5 1.8 enthusiast’s manual (you may want the 1.6i enthusiast’s manual instead) recommends inspection of the air filter every 6,000 miles. It should apparently be changed every 27,000 miles or 3 years. Armed with the workshop manual and a £12.77 brand new genuine Mazda air filter from MX5parts, I set to work.
Chances are that you could figure it out yourself, but on the off-chance that you’re somewhat timid or cagey about fiddling with your own car, here’s a step-by-step guide. (Usual disclaimers apply.) Apologies for the poor-quality camera-phone pictures.
That’s it! Drive off laughing like an idiot, enjoying the happier engine—and the consequently restored power.
