4 個 M18X1.5 45 ミリメートル栓 O2 酸素センサースペーサーテストパイプ延長エクステンダーアダプター CEL

The stock downpipe would not allow me to thread the spacer. I could only thread 180degrees then no room to continue threading as it bumped the downpipe. If someone is local to South Jersey, they can have mine for free.

Cheap Chinese junk. The threads on this are so poorly made that I cannot install it.

Says delivered but I never received anything. Won't buy again from this company 🤕

The WRX ECU is very sensitive. This product did not work for me. I ended up buying another catted converter that was Gesi certified.

I have more than multiple products from here and always on point as described fast shipping perfect thank you
