The ITG Pro-Filter for the Toyota Yaris GR replaces the standard panel filter as originally found in the air box. The advantages of a high performance foam-based ITG air filter are improved throttle response, increased bhp/torque, and being re-usable by cleaning. A paper filter needing to be changed every 3 – 4 years on average, you’re saving money by cleaning the ITG Pro-Filter and re-using it. A Pro-Filter fitted at next service will last at least five times as long as an equivalent, standard filter (under normal road use). Over the years, itg have created the lightest, most capable filters for all fields of motorsport, from Formula 1 to the World Rally Championship. The same design skills, advanced technology and attention to detail are also used to produce our Profilter range of high grade replacement filters for both road and competition use.
