Looking to get some input from both sides here, those who use, and those who don't use the back-fire screen with thier air-filters. It would seem I'm having a hard time getting a "perfect" seal using the screen, as this is the 2nd time I've found small traces of dust inside the air boot when using it. I oil my filters properly (same way I have for 20 years), grease the seal on the filter, and run a thin bead between the air boot and screen. I fit it, run my hand around to insure what appears to be a tight fit, yet still getting a small leak somewhere. Filters are new twin-air, Oil is No-Toil. Used it since it came out 10+ years ago and never had any issues. Going to go back to running without the screen and take my chances, but wondered if anyone else has had similar results, or it's just user error somewhere along the line.
