Cleaned Engine Bay & throttle body

ANMVQ

Nice work man, I'm cleaning my MAF's today, Just the MAF spray correct? An those TB's were horriable. Be they used cheap gas. Mine at 60k looked closer to the clean pic :/

Yea just buy the MAF cleaner, it literally takes 5 min or less to unscrew the MAF and spraying them down. And yea, i only use Premium gas in all my cars.

Cool thanx man, I'm picking up some CRC today on the way home. I cleaned my TB's a few when I bought the car and changed the plugs while I was in there. Just some finishing things before the dyno trip tomorrow

Good point on the gasoline. Quality gasolines have additives that help keep the intake tract clean. The same is true of quality engine oils. They have additives that keep the pcv valve and intake tract free of varnish and gum. Here is a link to Top Tier Gasoline web page. It has a list of gasolines that have effective cleaning packages in the blend.

Gasoline quality has no effect on the intake tract cleanliness. The gas is injected right into the cylinder at the intake valve in most modern fuel injected engines. The detergent packages will only have an effect on the intake valve, the combustion chamber, and pistons.

The throttle body gets gunked up from minute dust particles that make it past the air filters that combine with the oil vapors from the PCV valves that gets sucked back into the engine.
