Question

would a cold air intake help alot, one of my buddies had one on his 2000 blazer and it set off a mass airflow sensor so he is gunan sell it to me, mines a 96 so would my stuff be messedup to thanks.

an aftermarket intake will help the engine breath a bit better but the full bennifit is seen in the upper rpm range. the stock airbox only has a small hole in the front for air to flow through. you should not have an issue with the MAF sensor unless the filter is over oiled.
