* Brand: OEM (Original Equipment Manufacturer) coils from Mopar (Jeep's parts division) will generally be the most expensive. Aftermarket brands offer a wide range of prices and quality. Some reputable aftermarket brands include Bosch, Standard Motor Products, and Accel.
* Where you buy it: Dealerships will charge the most. Auto parts stores (like AutoZone, Advance Auto Parts, NAPA) will offer a range of prices depending on the brand. Online retailers like Amazon or eBay may offer the best prices but be cautious about counterfeit parts.
* Single coil vs. coil pack: The 2001 Jeep Cherokee Sport's engine (likely a 4.0L straight-6) might use individual coils for each spark plug or a coil pack. A coil pack (which contains multiple coils) will obviously be more expensive than a single coil.
* Condition (new vs. used): New parts are more expensive than used ones, but used parts carry a higher risk of failure.
Expect to pay anywhere from $20 to $100+ per coil. If it's a coil pack, expect to pay significantly more. For a single coil, you can probably find a decent aftermarket replacement for $30-$50. A coil pack could easily cost $100-$200 or more.
It's crucial to identify whether your Jeep uses individual coils or a coil pack before ordering. Checking a parts website using your VIN or engine details is recommended. Then compare prices from various retailers to find the best deal for a reputable brand.
