Genuine Toyota Parts are manufactured specifically for your year and model Toyota. They're exactly the same parts the vehicle was manufactured with, so they’re the best choice in terms of fit, performance and overall quality.
All Toyota Genuine Accessories purchased and fitted at new vehicle purchase are warranted for 3 years, or 100,000 km from the time of new vehicle purchase, whichever occurs first. However, It is important to note that if a non-genuine part is fitted to your Toyota and that part's failure or the incorrect fitment damages your vehicle, then that damage may not be covered by your Toyota Warranty.
Toyota recommends replacing air filter every 3000 kilometers or three months. If after checking and realizing it does not require changing, depending on the state of the filter, then one can proceed until it needs a new one. Remember always replace using a Genuine Toyota Filter.
Oil filters help protect your engine by trapping dirt and other contaminants while allowing the oil to flow to the engine. Toyota recommends changing oil filter and engine oil every 3000 kilometres.
