GREDDY AIRINX A/F-TYPE AIR FILTER SYSTEMDesigned specifically for use with popular JDM air flow meters which require application specific bolt-on adapters (or a more compact filter size, like the previous "mushroom" shaped Airinx AY-B), is the GReddy Airinx Air-Flow Meter Type System. The basic system is comprised of a specially-sized, large opening GReddy Airinx air filter, matching base plate along with an application specific molded Airinx AY airflow-meter adapter(s). GReddy offers two specific filter sizes, a smaller Airinx S with a 136mm dia. outlet to replace previous Airinx AY-SB filters and a medium sized Airinx M with a 172mm dia. outlet to replace previous Airinx AY-MB filters. This is especially ideal, when upgrading older GReddy Suction/Intake and Turbo kits which utilized previous Airinx AY-SB or AY-MB dome filters with application specific Airinx AY air-flow meter adapters.
AIRINX FILTER ELEMENTThe Airinx dry element filter with the molded polyurethane frame incorporates a specially-designed inverted structure with 3-layers of high-performance filtering elements in two specific compact sizes. The 136mm dia. A/F-type Airinx-S measures a compact H85 x T110mm dia. x B136mm dia. to approximate the dimensions of the previous “mushroom”-shaped Airinx AY-SB. (A/F-type Airinx-M: H105mm x T136mm dia. x 172mm dia. to replace Airinx AY-MB) The filter is decorated with molded GReddy Airinx logos and includes an additional GReddy emblem that can be attached to anywhere along the side of the filter element, 360deg. The dry Airinx element is ideal for air-flow meter use and is easily serviceable regular cleanings with mild soapy water and blowing with compressed air.
The key to getting these A/F-type filter bodies to work with the previous AY adapters is the use of a required, matching 136mm dia. baseplate adapter for the Airinx S or 172mm dia. baseplate adapter for the Airinx M. These powder-coated formed-metal baseplate adapters allow the use of the existing molded Airinx AY air-flow meter adapters (that you may already have from a GReddy suction/intake or turbo kit.) The baseplates also have provisions for mounting brackets and a port for optional sensors, if necessary.
There are two series of S and M-sized Airinx AY molded-polyurethane adapters. They come in various application specific shapes to match many popular Japanese air-flow meter types, like for the RB26, Z32, RB25, RB20, SR20, VQ35, 1JZ and 4G63. Also available are standard round adapters that range from 50mm all the way up to 100mm diameter, if you eventually decide to eliminate the factory air-flow meter in the future. (or have space confinements and require a lower-profile air filter assembly, than the standard Airinx S or M.)
