How much does a Tune-up cost for 1991 Lexus ls 400?

Answer 1

The cost for the parts for a major tune-up would run approximately $270-350, depending on the quality/brand. One of the biggest differentials is the cost of the spark plugs. For example, top of the line iridium plugs by Denso or NGK run close to $12 a piece (at an auto parts store, not the Lexus dealership which would be much higher); while the standard spark plugs are about $2 a piece. A typical major tune-up (if you're going to do it yourself) includes the spark plugs, distributor caps, rotors (the LS400 is unique in that it has two distributors, so it needs two caps and two rotors), air filter, oil filter, fuel filter, PCV valve, PCV valve grommet, and ignition wires. Labor is not included in the above price estimate; this is assuming you'll be doing the work yourself.
