Should I choose OEM or aftermarket for “junk car for sell”? | oem vs aftermarket junk car for sell

Choose by failure consequence, evidence, warranty, and labor cost. OEM can simplify specification matching; a documented aftermarket part can be suitable when its application data and quality controls are clear. FTC guidance says aftermarket use alone does not automatically void a vehicle warranty, although damage caused by a defective part or installation may be excluded.
