IMO it is very doubtful that filtration has anything to do with track temps. I was thinking that comment was a side bar, as a potential performance flaw was noticed.
I have not yet inspected the K&N for the GT. Maybe MAD could elaborate on his findings. I think he is saying the pleats run the oposite direction of the OEM filter ?. There are two things going on down there, suction from the motor and the ram air presurizing the box.
I'm sure we could get K&N to elaborate on the reasoning or even make a change if that were a problem. The owner has a GT and many Vipers, he is a real car guy like us. They dyno everything they do. But, what MAD is suggesting would not show on a dyno IMO. He may have uncovered something K&N would love to hear.
If we think it is a concern I could get K&N to give us more info. It's not like them to miss a detail like this, but not impossible either. The pleat orientaion is a very easy change if it is needed IMO.
When K&N comes up, there are various opinions about the product that come up as well. I have personally gotten involved in this controversy and offer below what I found on inspection.
As for the filter itself, it's gotten much better over the last few years.......
In some circles they have gotten a bad rap as it is thought an oiled media will deposit a film on the mass air wire, thus allowing to collect fine dirt easier. When this happens the feedback from the heated wire can be confused by the ECM and adjust for something that is not there. The result could be a bad idle Lumpy as it would more often dump excess fuel in this situation. The fix was simple, clean the wire with a spray of electronic cleaner.
True or Not?. I have been through the K&N lab and I would say false at this point. They have had a state of the art facility for the last few years. They do the CART/ IRL/ Indy car filters, each is tested and serial numbered. All cars in those series were running their products. But that does not mean much for a daily driver.
Enter R&D and the Dirt GUY. He has a full lab where they test dirt at different micron levels to insure each filter provides the proper amount of protection to the engine and Mass air wire. Each filter design has many, many hours on the test device to pass. They literally suck dirt of different micron levels through the filter 24 hours a day for many days. The Dirt guy ( I just call him that) has many jars of certified, numbered dirt/dust from all over the world. They did this testing as their had been rumors from an OEM's that they would not warranty a K&N filter. The Moss Magnusen act requires them to do so. K&N has provided the testing and the Mfg. Retracted the statement/warning.
When cleaning your K&N, the trick is to not over oil the filter and wait for the oil to flow evenly across the mesh. Over oiled filters run too quickly can cause the Mass Air wire issue some had reported. I was critical of the news on a forum and went to the plant to find out the real deal. After I left I was not longer skeptical. I had seen the mfg. process in 1989 and I have to say the two are night and day different. Same idea, but the control is much different. What once was, is not always what now is. I am running the product in my Z06 and have no worries now, or any issues.
The test facility and R&D dept are some of the most impressive in the aftermarket now. For local GT owners, I am sure the owner would host us for a tour if any one had any interest.
