I've seen this factory upgrade get on a couple of web sites. Has anyone heard anything good or bad about it? I'm sure it can't breath as well as some of the monsterous open air elements on the market.

 

Which one are you talking about, the Tymar or AIS?

 

Neither, this is actually a FORD INTAKE UPGRADE

Actually, that is the AIS (made by Ford). A lot of people on FTE use this system and seem pretty happy with it. It won't flow quite as much air as an open element filter, but it flows a lot more air than the stock setup and filters much better. You also don't have to worry about warranty issues since it's a Ford product.

 

I have one. Simple to install, filters very good.

 

I like mine, the filter is huge. I might of went with the tymar but I was concerned for the warranty issues. Now that they are going to stick a probe up my tailpipe as of last month I might not be able to mod any further after warranty runs out.

 

I have one on my 01 and like it very much. They can be purchased cheaper than that price!

Just pull your chip or use the tuner to restore the truck to stock tune before you go to the test station.

 

Yeah but if I chipped my truck I would get an exhaust upgrade first, that would be the failing point.

 

Here in Washington they don't care how big the exhaust is, just that the exhaust leaving it is within specs. For diesels, that means very little smoke, and a stock tune will pass the opacity test with flying colors.

 

The gassers I have had tested here they go with a mirror and look for the cat.

 

Did your truck have a factory cat? Not all of them do, how could they prove your truck was factory equipped with one.

 

It's recorded with the VIN number and what the truck was equipped with at production. All they have to do is scan the bar code and everything pops up on the computer. (At least in WA that's how it goes.) I still don't think that a large pipe will effect the test result other than making the exhaust even more to thier liking. A bigger pipe on a diesel will reduce smoke a lot. As far as the cat goes you can always gut it but then run the risk of marginal exhaust readings. It's a guaranteed fail on a gasser, but I don't know without a lot of study on rules and specs state by state if that would be a failure for a diesel. It's real easy in WA. You just have to pass an opacity test which is a fancy way of seeing how much smoke you make and putting a limit on that.

 

whers the cheeeepest place to get the ais or tymar filter? also which is the most reasonable to buy replacement elements?
