The maintenance cleaning/oiling of the K&N filter is probably what holds people back from purchasing it despite any increases in HP or mileage.zfiero said:...Alot of people don't like K&N I have had them in every vehicle I ever owned my last trunk was a chevy blazer it had 305,000 miles and still running the orginal engine, I put a k&N in at 10,000 miles. Just follow the proper cleaning and oiling procedures when it needs to be cleaned.
The bolts are a "star" pattern, but I'm scrambling to remember the sizegravenwolf said:what kind of wrench and how long should it be to take the bolts off the air filter?
BigTallV said:See your owners manual under the "Checking Things Under the Hood" section, specifically the engine compartment overview. Air cleaner is within housing toward drivers side of engine bay. Standard OE or after-market equivalent replacement filter will do just fine. I only ran a K&N filter on a '78 Monza Spyder (V8) that I used to have where I wanted to muster every last HP I could squeak out. So can't speak to its use on the Outlook engine.
As far as warranty purposes go, use of 3rd party products shouldn't void your warranty of themselves unless those products are proven to be the cause/fault.
I had a '79 Monza Sypder, loved the car, but it was a maintenance nightmare! Cool looking though, and fun. blue with black stripes/graphics. Cheers!
Replacing the air filter is simple but some of the screws may be hard to get two. The size for the wrench is the torx t25 and if you can find one that is about 12 to 24 inches long it will save some hassle. I have a 8 inch one and it was hard to find a grip on the back screws. I went with the napa gold air filter and seems to be fine with no change to the gas mileage or performance.AA/78U said:The bolts are a "star" pattern, but I'm scrambling to remember the size
Check out this thread from the Acadia forum; I'm thinking you have the same size
Is there much of a cost difference for a K&N vs AC Delco?Cris4029 said:I ended up going with the K&N air filter replacement. I've used them in all my vehicles so I have no problem with taking time to clean them manually. Like was stated it was a Torx T25 bit. I went with removing all the screws completely. Unfortunately the Mass Air Sensor and the short hose between don't allow for too much movement so I went ahead and removed it all the way to just before the throttle body. you will need a slightly larger Torx T27 for the 2 bolts holding the MAS to the filter box lid. Very easy replacement process.

I had an '80 base Monza hatch and my sister had a '79 2+2, both 4 cyl. 4 speeds. Good looking and nimble handling, but absolute lemons. Poorly engineered and sloppily assembled. I miss mine though. ;Dcawarson said:I had a '79 Monza Sypder, loved the car, but it was a maintenance nightmare! Cool looking though, and fun. blue with black stripes/graphics.
So you would almost have to install the OEM air filter again before you go in just to be safe?ls973800 said:I've read that K&N filters mess with the MAF sensor and you'll get a CEL, dont know if it's just certain vehicles or what
I had read on one of the Ford forums that Ford service departments were told to check for the use of a K&N filter and if found, to determine if the CEL was a result of that filter oil and deny any warranty work involving that system.
