1988 Sunbird valves look and function like new

Subject: BG Air Intake System Cleaner

Dear Sir/Madam,

I am a retired post graduate British mechanical engineer who cannot praise the above product enough. In fact, I have good reason to believe this product alone is the main factor in achieving a longevity of 160K miles with the 4-cylinder 2.L engine in my 1988 Pontiac Sunbird, since I have used it regularly since the car was new. I am astounded by the fact that the ignition compression of the engine is the same now as when the engine was new.

Also, my maintenance costs have been very low because of this product such that the original EGR (exhaust gas recirculation) valve still functions correctly on the car.

It is worthy of note, I took the head off the engine after 100K miles and the valves and the valve seats looked like new and had no carbon deposits, as well as the fact that the valve springs were functioning correctly. I have had no problems with the single point fuel injector either.

I am your best advertisement,
Many thanks,
