These models utilize 3 studs and nuts to connect the exhaust downpipe to the back of the turbocharger. It is common for these to suffer from corrosion over time and often break during disassembly. These are the correct, Volvo OEM part to properly replace these studs if needed.
Aftermarket parts are a reasonably priced and good alternative to OE products. We often supply aftermarket products in place of OE parts that are no longer available as well.
Some items will be better than stock or considered an upgrade from the OE design in the aftermarket brand.
Other items will work as a less expensive alternative to stock.
We will not sell a product that we do not believe in, so rest assured you are fine with the aftermarket brand in most applications!
If you have any questions, contact our customer service team to advise on the best aftermarket products for your Volvo.
