I have no idea what valve controls are in our 08 Altima, but for a car that size [read as very roomie!] to be hauled around by a 2.5L 4cyl as well as it runs is true feat of science. Both in the CVT trans and the engine! It also already out of the box gets 1-2mpg better mileage than the 98 does! or ever did ! -- Mark Price Morgantown, WV 1969 AMC Rambler, 4.0L, EFI, T-5 2004 Grand Cherokee Laredo, 4.7L, Quadratrac II " I realize that death is inevitable. I just don't want to be around when it happens!
