Review on 🔥 Revitalize Your Fuel System with Red Line's Complete SI-1 Fuel System Cleaner - Gas and Injector Additive Treatment (12 Pack Case) by Mark Hanson

Redline SI 1 is the most efficient injector and cylinder head cleaner. Why? It has the highest concentration (30-50%) of PEA, a polyetheramine. PEA is considered the most effective chemical cleaner for injection systems, cylinder heads and valve heads/stems. Do your research on Redline and the web, Google. It also cleans the upper cylinder. The competition is closing in, but the Redline seems to be holding on to No. 1 status. One reviewer seemed very upset that its gas mileage didn't skyrocket. Don't expect this to be common sense. BMW put the Redline SI 1 on the official parts list years ago and with good reason: it works! I have used Redline products for decades and pay more because they are some of the very best, if not the best, at what they do.
