Restore Lost Power, Improve Idle Quality, Restore MPG!

A common fault of modern direct-injection engines, detrimental carbon build-up on the rear of the intake valves robs you of performance, gives a poor idle, misfires and poor fuel economy!

Restore your  engine to top condition with our intake port walnut blasting / decarburising service. 

The detrimental carbon build up is an unwanted by-product of modern direct fuel injection systems, & affects many models across many manufacturers, not just BMW!   

Some indicators that your BMW may need this service: 

  • General loss of power 
  • Flat-spots throughout the rev range 
  • Poor or sluggish throttle response 
  • Misfires, particularly when cold 
  • Poor fuel economy 
  • Poor cold idle quality (rough idle etc) 

We duplicate the BMW main dealer service by using our professional media blasting tooling for this application, with genuine  BMW intake port adaptors. 

After removing the intake manifold & correctly preparing the intake system for cleaning we use our equipment to ‘blast’  ground cleaning media into the cylinder head intake ports at high velocity while safely & simultaneously extracting them along  with the dislodged carbon debris.  

When reassembling, we include new genuine BMW intake manifold & throttle body gaskets* (where applicable*) each time. 

  • To ensure the continued reliability & performance of your engine we typically recommend this service be undertaken  approximately every 50,000 miles.  

Prices from just £299 inc VAT. Please enquire for more information regarding your model.
