A long overdue review from me, sorry for the delay Elton!

first impressions:
no difference...wasn't really expecting much to begin with as I was never a believer of such products, with the recent exception of stuff Elton sells...heheh!

Day 2! :
started the car in the morning and hey! The mitsubishi heavy metal band in my engine bay seems to have started playing a lighter tune! Interesting...

It's been almost 2 weeks now, and I think I can safely say that it works! In my engine bay now is a practicing symphony orchestra. Heheh...the hydraulic lifters are not 100% quiet, I can still hear them juuuust a little, but hey, better than a really bad heavy metal band playing under there.

another great product Elton! Cheers!
