An upgraded V6 hyrbid engine burns fuel twenty percent more efficiently than prior generations of Lexus SUVs. We don't have time to get into all the other exemplary details, but you know what you have, and you need to treat it right. Don't upgrade or add-on with just any old part. Find the custom-fit parts and accessories you need on the list that follows, and keep your Lexus RX450h as it should be: the envy of every other crossover driver on the road today.
