Super easy experience to book and get my car in. Super clear that these guys care about their work and their customers. Really appreciate Marc looking further into a weird electrical issue with my car too. And really appreciate the team letting me take a meeting in their office. 5/5!

The most honest and reliable mechanics I've ever been to. I had an issue with my electric window being stuck down and one of the guys fixed it without additional charge. As a struggling student, this took a lot of stress off my shoulders

Very disappointed spent over 10k on engine!! Drove it one day did 80ks engine went bang . We had to fix it our selves over Christmas. Cost 7k to fix found many things that a so called expert should have seen inc a rivet in sump . Can’t

Mark at EFI is awsome, honest and professional my clubsport tourer is a different car now and I highly recommend them because they are the best at what they do and they will always make time to assist and advise you at every stage and

The vf clubsport that said he spent 14k with mark and called him a lawnmower mechanic is a push bike mechanic knows nothing about nothing puts stale fuel in his car does the damage and blames others I know this for a fact as owner not

Im just beginning my journey with Mark and the team at Northern EFI, they have been absolutely brilliant. Mark sorted out everything to get my 72 Chevelle on the road including road worthy, auto elec work and even the VASS engineer

Got my car serviced last week, took my car to 2 other places that couldn't fix an issue I was having. Got it looked at by Mark, he sorted everything out. Top guy great shop to get your cars sorted.

Marc went above and beyond to help me with my car, honest, professional and reliable service, anyone in the northern suburbs go and see the team at northern efi, you don’t be disappointed.

Marc and the team at northern efi helped me out a lot with my ford ute working endless hours to fix my issues and am over the moon with how the car performs after the tune marc did to it.

Big Thanks to Mark and the Team Helped me Tune my Ls Engine Really Happy Mark did an amazing Job God Bless you Mark , Your Team and Your business. Thank you Heaps Brother Arash :)

Great team at Northern EFI & Mechanical, friendly, trustworthy and helpful. Always happy to explain and show what has been changed on my car. Very happy with my continued service.

Took them 3 monts to order and replace 1 sensor ! Every time they said they will call me back, never happened When i turn up there, they ignore you for good half an hour !

Most knowledgeable team yet so humble and reasonably priced. Also highly recommended for work on classic cars, high performance sportscars and dyno tuning.

Broke down near Latrobe University and didn't know what to do. Northern EFI were just around the corner. Mark got me out of a really sticky situation.

Took my vf lsa clubby to mark for some mods spent $14k to later find out my lawnmower mechanic could of done better. Over boosted engine

Great place. Did a really good job replacing my clutch, and got me a great price for it too. Very friendly and helpful staff.
