Says it is for gasoline powered 4, 6, 8 cylinder cars.....don't know the implications of a three cylinder in this case for the tach...but for the other stuff, it is a case of the sensors being able to be attached to the motor. You've got oil temp, oil pressure and water temp on there too. So all these have to have pick ups attached to the cooling system and oil system. If you can't do it yourself, I would shop the cost of the install first....and if it is expensive to do, I would shell out for a VDO or similar brand of guage.
20% of the cost of this item is VAT (taxes) also, so what is the quality???? It does look cool though.
