Hey All, Im in the process of renewing my Manufacturers Warranty on my Sportivo with Toyota and have read their warranty booklet.... I came across the following note...... - What is not covered - Item 7. Any claim where the damage to a covered component was caused by a non-covered component. This basically means your Cold Air, Air Filters, UNI chips, Exhausts, Extractors so on and so forth.... Now we all now these items have no negative affect on the engine but Toyota and all other Manufacturers will screw you on this item..... So save your money and dont bother with a false sense of security by renewing your warranty...its not worth the $1,200.00. You could spend that on upgrading your sound system....... Cheers,
