Would it be worth it to put a cold air intake on a 91 Buick Riviera?
A cold air intake is good if it cools the intake air enough to increase the density of the air coming into the engine. An oiled air filter ( like KN) however will contaminate the MAF sensor with oil and dirt if it is a heated wire type. 91 may have the heated wire type. An oiled air filter is not recommended for that application. Cooling the air condenses the molecules and makes the air more dense. That means more air by volume. That means you can add more fuel, that is in theory. Reality is the car's fuel control system is going to try to keep the mixture entering the engine at 14.7 :1 for best control of the three main pollutants and optimal catalyst performance. To be any good it would need an ice box and you would have to get the computer programmed to run slightly richer. The short answer here is: You will not significantly improve the performance, you will increase the maintenace cost, you will increase the intake noise and you will tend to use a heavier foot so the fuel economy will go down. But it will look and sound cool.
on the least get the fluid and clear out replaced, on no account flow to a variety of quickie fluid flush places. i might think of the dealership might do it suitable additionally. in my view, i take advantage of my very own technique for flushing - this is composed of cleansing the pan changing the clear out. After reassembly do away with the return transmission line and divert it right into a gallon field. upload 5 quarts to the transmission, initiate the vehicle and with brakes utilized shift into tension, this might pump exceptionally much each and every of the relax previous fluid out very as we talk, pausing to function some to maintain from figuring out. as quickly as you get to approximately 5 quarts out of the line the fluid would be particularly sparkling. that's the secure way of flushing I even have achieved numerous situations and no subjects. there's a grain of reality to the statements approximately no longer flushing because of the fact that's going to screw up a transmission. I even have yet another hypothesis approximately flushing. a million. how a lot of human beings do no longer even think of approximately their transmissions till they're performing unusual? you are going to be considered one of them. i don't be conscious of in case you have been the unique proprietor. 2. as quickly as taking it to get a flush achieved the transmission keeps to act unusual then quickly fails so blame the shop! 3 loss of upkeep - a transmission shop surely needs to be hectic whilst somebody such as you pulls up and that they seem the the fluid situation and the mileage. 4. If it have been my shop i will no longer opt to do it in any respect till there some information that it were serviced formerly.
You don't say what engine you have.3.8 V6? A CAI might save you a bit on gas mileage, if you pair it with a decent air box and a KN.
what good does it do to have a cold air intake? if it was a good thing dont you think the manufacturer would have put it on at the factory?
All you can do is drop the pan and change the filter, you will still have fluid in the converter. Take it to any jiffy lube for about 80.00 they will flush it. depending on your milage,you may need a new filter . Some people say that if you have alot of miles on it and never flushed it before it may do more damage than good !!! Good luck !!
