Collection: Race Rally Track Performance Upgrades

Mr Injector UK serviced four DI injectors from my A4 2.0 TFSI engine, previously with a persistent mis-fire, especially when cold and sometimes after a long journey. They were returned by next-day delivery, clean, with seals and accessories, ready to refit. The car is now perfectly smooth and slightly more economical. Communication by email was great throughout. The technical report was reassuring. A great result at a fraction of the price of new injectors. Thank you!

Just had five Bosch injectors serviced with James, from my initial email through to receiving the refurbished items communication was very thorough. Price was very reasonable and the injectors are as good as new, highly recommended!

Used them a couple of times now. Speedy service, friendly and happy to help. Good value, would highly recommend.

Really good service. James was Friendly, helpful and responded to any questions that I had via email. Would absolutely recommend using them.The injectors from my 1987 Jeep are BENDIX which are an unusual make, after a phone call and some pictures sent via email, James was able to confirm that they could be refurbished. Glad that I sent these to be checked TBH as it was discovered that they were leaking from the actual body's. I was advised that they were unfortunately not repairable and if used would cause an engine fire!!. Mr Injector has saved me from a potentially dangerous situation.. Thanks James 👍

5 star service

James did a cracking job on my old Bosch injectors from My Alpina. They really did look old and grotty when removed, returned looking like new, great price and communication too. Really pleased and the car is driving better than before! Job Jobbed!

Excellent service, injectors look like new.

Outstanding service on my 40+ year old injectors. Very helpfull and all as promised plus a very informative written report. Highly recommended.
