About this product
KNECHT air filter (LX 1245) maintains peak combustion efficiency by delivering a clean, metered airflow to the intake manifold while blocking dust, pollen, and fine road debris. Filter geometry — Diameter [mm]: 85, 0 mm, Height [mm]: 70, 0 mm, Height 1 [mm]: 70 mm, Filter type: Stainless Steel — is optimised to maximise surface area within the airbox housing, reducing restriction and extending service intervals without sacrificing filtration efficiency. Cross-references OE filter numbers: 1082111, 10821114, 11172907, 11584 and 37 more. KNECHT air filtration elements are tested to ISO 5011 standards for fractional efficiency, ensuring the engine management system receives clean air data for accurate fuelling across all load points. Air filters should be inspected every 12,000–15,000 miles and replaced when visibly dirty or at least once a year — vehicles driven on dusty or unpaved roads may need more frequent changes. Symptoms of a clogged air filter include reduced acceleration, lower fuel economy, a rough idle, and in extreme cases the engine management light illuminating due to incorrect air-fuel ratios. Replacing an air filter is one of the simplest DIY tasks on any car — usually just unclip the airbox lid, lift out the old element, drop in the new one, and re-seal; no tools required on most vehicles. Choose a filter that matches the OEM filtration efficiency rating (typically 99%+ particle capture) — cheaper filters with lower efficiency let more abrasive particles through to cylinder bores and valve stems. A clean air filter can improve fuel efficiency by up to 10% and helps your engine breathe properly, extending the life of downstream sensors such as the mass airflow meter and oxygen sensors. Every part is dispatched from our UK warehouse with a 30-day money-back guarantee and free hassle-free returns.
