Rapid response shipping is great

Rapid response shipping is great. My 2008 Pajero (220000kms) really likes your Fuel Enhacwr which I have been using regularly for the past 5 years and 100,000kms. The next 100000kms though are the vital ones!

2nd purchase

2nd purchase. Great product. Took a few applications but engine ran smoother. Injector feedback values retuned to manufacturers specification. Have newer vehicle now and will add CRD fuel enhancer at every fill. Much more cost effective than new injectors!

Recommend CEM products to everyone.

The best product out there that shows clear and positive results. Easy to deal with and quick delivery. Used these in all our vehicles with great results, better performance and reduced/stopped blowby. {engine with 330,000km and no blowby}. Nothing else compares.
