Tune-up & Injector Ultrasonic Cleaning.
Why use Ultrasonic EFI Injector cleaning?
Ultrasonic Petrol Injector cleaning uses high-frequency, high-intensity sound waves in a liquid to enhance the removal of foreign contaminants from surfaces submerged in an ultrasonically activated liquid. This is the only process that removes all contaminates from the fine internal injector passages.

The Tune-up process begins with an electronic diagnosis, identifying the engine and support systems that have worn or else drifted out of adjustment.
Let's dismiss the myth that a Tune-up is the wave of the magic wand because each vehicle is an individual case and at Highways your car will be carefully inspected and diagnosed to discover just what needs to be attended to and returned to manufacturer's specifications.
When the diagnostic test results are in we do a costing and contact you for approval. We are happy to SMS or email pictures of any parts we reccomend for replacement. The price we quote is the price you pay.

Why do EFI Injectors need to be cleaned and serviced?

Every time you shut down a hot engine a small amount of residue adds to the already present build up in the injectors. The more frequent the stops, the more rapidly the build-up accumulates.
This accumulation eventually reduces the flow of fuel through the injector and disrupts its spray pattern, causing the engine to run lean. This can manifest itself in a number of ways, although the most common is driveability problems such as flat spots and hesitations.
The cost of the above varies with makes and models therefore we are happy to work out a custom servicing plan that is best for you and your car and at the best price.
