Parts for your 2021 Suzuki Splash-Air filter

2021 Suzuki Splash air-filter: purpose, care, and when to replace

It’s relevant and fitted. Technical documentation confirms the Suzuki Splash uses a conventional engine air-cleaner element (paper filter). Suzuki’s workshop manual for the Splash/Ritz (RB platform, K10B/K12B petrol and 1.3 DDiS diesel), the factory owner’s manual maintenance section, and Suzuki’s electronic parts catalogue all list an “Air Cleaner” and “Air Cleaner Element” for these engines. Maruti Suzuki Ritz (the Indian-market twin to the Splash) manuals list routine inspection and replacement of the air filter as well. So, any 2021-registered Splash on the road uses an intake air filter.

This air-filter is there to keep dust, grit, and bugs out of the engine while letting plenty of clean air in. That clean air is crucial for the Splash’s fuel injection to meter the right mix, protect cylinder walls, and keep sensors like the MAF happy. A fresh filter helps the little Suzuki breathe freely, smoothing throttle response and helping fuel economy—especially noticeable around town and on open-road runs across Aussie and Kiwi conditions.

As part of regular servicing, the air-filter should be checked at each service and replaced at sensible intervals. Many owners follow 15,000–20,000 km or 12 months, whichever comes first, but dusty/gravel use often calls for earlier changes. Under the bonnet, the filter sits in the airbox, pop the clips or screws, lift the lid, and you’ll see the rectangular element. If it’s dark, clogged, or the pleats are oily or collapsing, it’s due. Always seat the new element properly so the lid seals all the way around—unfiltered air sneaking past is worse than a dirty filter.

Signs it’s past its best include a slight drop in pep, higher fuel use, or a muted whooshing intake sound. Sticking with a quality OEM-style paper element is the easiest, low-fuss option for daily driving. Reusable oiled filters can work, but they need careful cleaning and very light re-oiling—too much oil can foul airflow sensors. For most Splash owners, a simple paper replacement at service time is the most reliable, cost-effective approach.

• Inspect at each service, replace about every 15,000–20,000 km (sooner for dusty use).
• Keep the airbox clean when swapping the element, wipe out leaves and grit.
• Avoid compressed-air blasting from the dirty side—it can tear the media.

FAQs

How often should the 2021 Suzuki Splash air-filter be replaced?
Most owners replace it every 15,000–20,000 km or 12 months. If the car sees gravel roads, coastal sand, or lots of roadworks, inspect more often and change earlier. Always follow the service schedule in the owner’s manual for your engine.

Where is the air-filter and can it be changed at home?
It’s inside the plastic airbox under the bonnet. Release the clips or screws, lift the lid, swap the element, and refit the lid evenly so it seals. It’s a straightforward DIY job with basic tools and a few minutes’ patience.

Should they use a reusable performance filter or stick with OEM paper?
For everyday commuting and weekend trips, a quality OEM-style paper filter is fuss-free and protects well. Reusable oiled filters need careful maintenance and light oiling to avoid sensor contamination, they’re best for enthusiasts willing to service them properly.
