Review: This is truly a no brainer. Couple of bucks to remove that pesky engine light AND pass e-test for my 05 BMW. Required some modification for Bosch 02 sensors, best to buy two per cat drill bottom one out completely hone out the other without losing the bottom hole on the second and use two if clearance allows keep small hole on the first one . Worked like a charm cleared codes and 300km so far no light . I will tell everyone I know who gets a cat efficiency code to get these. Thousands of dollars saved because of metal threaded spacers! Don't ever waste money on new cats. The government can kiss my butt or buy me new cats on their dime (technically my and your dimes) if it wants to. I'll buy these.
Review: Ottimo e sicuro con il servizio trasparente.
