Haima S7 Air Filter (Complete) – Part No.: SA11-13-320

Let’s keep it simple—this isn’t just a “piece of filter paper” in your Haima S7. It’s the key protective barrier for the engine’s intake system: a durable, complete filter unit made of high-density composite fiber (or premium paper) wrapped in a rigid plastic frame, with a rubber seal around the edge. Mounted inside the S7’s air filter box (usually near the front of the engine bay), it sits between the outside air and the engine’s intake manifold. Think of it as the “engine’s ‘nose filter’”: without it, dirt, dust, and sand get sucked into the engine—causing premature wear, reduced power, and even costly damage.

This complete air filter is exclusive to Haima S7—always check your vehicle’s VIN to confirm fitment! It’s tailored to the S7’s specs: its size and shape perfectly match the air filter box (no gaps for unfiltered air to slip through), its filtration density aligns with the S7 engine’s airflow needs (blocks 杂质 without restricting air), and its rubber seal fits tightly against the box (ensures a full seal). Grab a generic air filter instead? You’ll run into trouble: wrong size (leaks unfiltered air), poor filtration (lets dirt in), or too dense (chokes airflow, killing power).

Core Jobs: Protect the Engine, Boost Performance & Save Fuel

As a must-have for the S7’s engine health, it does three key jobs that keep your car running smoothly:

Filter out harmful debris: When the engine sucks in air for combustion, the filter traps dirt, dust, sand, pollen, and small bugs—stopping them from entering the cylinders. Even tiny particles (as small as 0.1mm) can scratch cylinder walls or damage piston rings if unfiltered, leading to engine oil leaks or reduced compression.

Maintain steady airflow: Its porous, high-density material filters impurities while letting enough clean air flow into the engine. This ensures the air-fuel mixture stays balanced (critical for efficient combustion), keeping the S7’s acceleration responsive and avoiding power loss.

Extend engine life & save fuel: By preventing debris from wearing internal engine parts, it reduces the need for early repairs and keeps the engine running efficiently. A clean filter can even improve fuel economy by 1–3%—clogged or poor filters force the engine to work harder, burning more gas.

This SA11-13-320 air filter only fits Haima S7—wrong fit means engine risk:

Fits These: All Haima S7 variants (matches the air filter box size, airflow specs, and seal dimensions—confirm with VIN).

Won’t Fit These:

Other Haima models: Like S5, 7X, or M3—different air filter box designs and engine airflow needs (filter can’t seal or supply enough air).

Non-Haima vehicles: Even if similar in size, the frame shape and seal position differ (leaks unfiltered air or blocks airflow).

S7 with modified intake systems: Aftermarket cold air intakes or intake manifolds need custom filters—original filter can’t adapt, causing fit or filtration issues.

 Installation & Upkeep (Easy DIY—No Pros Needed!)

Installation: Simple Enough for Most Drivers

Replacing this air filter is one of the easiest DIY maintenance tasks—just follow these steps:

Locate the air filter box: Open the S7’s hood—look for a black plastic box (usually with clips or screws) near the front, connected to a large hose (the intake tube).

Open the box: Unclip the plastic latches or unscrew the bolts holding the box lid down—lift the lid carefully.

Replace the old filter: Pull out the old filter (note its orientation—match it with the new one), wipe any dust from the box interior, then drop SA11-13-320 into place (ensure the rubber seal presses tightly against the box).

Close the box: Put the lid back on, reclip or retighten the bolts—and you’re done!

Maintenance: Regular Checks to Keep It Effective

Replace on schedule: Haima recommends replacing the air filter every 10,000–15,000km (or once a year). If you drive in dusty areas (e.g., dirt roads, construction zones), replace it every 5,000–7,000km—clogged filters hurt performance.

Check monthly: Open the air filter box occasionally to inspect the filter—if it’s covered in thick dust, dirt, or oil, replace it early (don’t tap or wash it—this damages the filter media).

Avoid “cleaning” reusable filters: This SA11-13-320 is a disposable filter—reusable aftermarket ones need special cleaning, but the original is designed to be replaced, not washed.

Summary: Haima S7 Complete Air Filter (SA11-13-320)

This is an exclusive complete air filter for Haima S7—confirm the vehicle’s VIN for fitment. It consists of high-density composite fiber/premium paper filter media, a rigid plastic frame, and a rubber seal, mounted inside the S7’s air filter box (near the engine bay front), acting as the engine’s intake protective barrier.

Its core functions: Trap 95%+ of debris (dust, sand, bugs) to prevent cylinder/piston ring damage; maintain steady airflow for balanced air-fuel mixture (avoids power loss); extend engine life and improve fuel economy by 1–3%.

It only fits all Haima S7 variants— incompatible with other Haima models (e.g., S5, 7X), non-Haima vehicles, or S7 with modified intake systems. Installation is DIY: locate the filter box, open it, replace the old filter (match orientation), and close the box. Maintenance requires replacement every 10,000–15,000km (5,000–7,000km in dusty areas), monthly inspections, and no washing (it’s disposable). Original parts ensure good filtration, seal, and airflow—aftermarket ones risk poor protection or restricted airflow.
