4 STK M18*1,5 CEL sjekkmotorlys O2-sensor Testrørforlengelse Forlenger Adapter Avstandsstykke 45 mm

I bought 2 catalysts converters not from the USA & my check Engine came on the first week I had the cats I stalled so I talked to a mechanic & he said to try these 02 spacer Extensions had to remove the the inner flow screen & like magic . My check Engine light been off for 2 weeks now
So I can't believe this little $ 45 for both fix actually works. I'm a believer . Works for me . AAA +++
