Porsche 356 Guru "The Maestro" The Late Harry Pellow once wrote about his trials and tribulations with the early California smog tests. He'd put a set of fouled plugs and dirty air filter in his old Mercedes and take it in for the test to intentionally flunk it. They'd give him the opportunity to make repairs and re-test, and if the re-test was marginally better they'd pass him. So he'd put a new set of plugs and a new air filter and pass with flying colors the next time.
