Terrafirma - Power Plus Foam Air Filter - TD4

The Terrafirma Power Plus Foam Air Filter (TD4) is a premium serviceable air filter equivalent to PHE500060, designed for Defender 90, 110, and 130 models. Manufactured by Pipercross, industry leaders in foam filter technology, this filter delivers 30% increased airflow compared to the original paper element while maintaining a reusable, lifetime design without added induction noise. Unlike standard paper or cotton filters that restrict airflow when trapping dirt, Terrafirma's advanced deep foam construction allows air to bypass trapped particles. Independent MIRA testing confirms that Pipercross foam retains more than twice the dust capacity of competing filter types without compromising airflow. The specialized polyurethane foam construction offers superior performance and durability over traditional paper alternatives. The triple-layer design progressively filters from coarse to fine, capturing dirt particles in the outer layers while the inner layer provides exceptional filtration and engine protection. When fully saturated, the filter is easily cleaned and re-oiled for continued use. The Power Plus Panel features a radical foam and stainless steel frame design engineered for maximum flow performance. Its dual-layer construction—combining a 5mm 60PPI outer layer with a 20mm 20PPI inner layer—delivers 22.1% greater airflow than the standard panel while enhancing dirt retention. This premium option is ideal for high-performance engines demanding superior intake flow rates.
