It is your responsibility to purchase the correct part. Very often there is more than one part available per application as auto makers often switch midyear. eCRATER’s compatibility system does not allow sellers to account for any variations by VIN. If you don’t have the part number, you can get it from any dealership by providing your VIN. This way you can avoid unnecessary hassle and return shipping costs. We provide part numbers and high resolution photos, but if you do not check them we cannot guarantee fitment. 2011 Series Lt1/Lt4 Optispark Distributor With Upgraded Aip Sensor Don’t let the price fool you, this distributor is built for reliable function.
