What warranty do your performance parts have?

Most performance parts are sold by the manufacturers as "for race use only", which in practice means they carry no manufacturer warranty. Racedom nevertheless offers a 2-year warranty (and sometimes more) as long as the product has not been physically altered or damaged (e.g. deformed, overheated, burnt). Electronic gauges such as AEM X-Series have a 2-year warranty. Wear parts such as wideband O2 sensors are excluded.
