ThunderSpark Coil Boots and Coil Boot Kits are OE Replacement components designed to restore critical spark isolation and electrical connection in modern ignition systems. In coil-on-plug (COP) or coil-near-plug (CNP) configurations, coil boots serve as the insulative path between the ignition coil and the spark plug. Over time, these boots can degrade due to heat, vibration, or chemical exposure—leading to arc-through, misfires, or hard starting. Walker coil boots are engineered to match OE specifications for dielectric strength, length, and terminal fitment, ensuring proper high-voltage insulation and secure coil-to-plug contact. Each boot is constructed from premium silicone and other high-temperature materials to withstand engine bay conditions. Coil Boot Kits include all necessary components—boots, springs, and insulators—for full-cylinder service, making them ideal for ignition tune-ups or preventative maintenance. Whether replacing a single boot or servicing an entire engine set, Walker Coil Boots and Kits help restore ignition reliability, engine smoothness, and emissions performance.
Characteristics include:
Heat & Chemical Resistant: Constructed from high-temp silicone and reinforced materials to resist oil, fuel, and under-hood heat.
Complete Kit Coverage: Coil Boot Kits include boots, springs, and insulators needed for full cylinder replacement—ideal for tune-ups and repairs.
OE Replacement Quality: Engineered to match OE dielectric strength, boot length, and connector geometry for consistent performance.
Exact OE Fit: Designed for 100% compatibility with factory ignition coils and spark plugs for coil-on-plug and coil-near-plug systems.
Restores Ignition Insulation: Replaces worn or cracked boots to ensure proper spark isolation and prevent voltage loss.

Excellent quality and fast shipping!
I’m very happy with my purchase from Pioneer Parts. The brake rotors arrived quickly, were well packaged, and the quality looks excellent. The fit and finish are great, and everything matched the description for VW Jetta 2013 TDI,Great service, fast delivery, and good-quality parts. I would definitely order from Pioneer Parts again!
Highly recommended! 🚗🔧⭐⭐⭐⭐⭐
The rotors and pads were perfect. A little disappointed the the front pads didn't come with new hardware, but the rear ones did. Would have been 5 star had the front hardware been included. Delivery was fast, and parts were exact.
Looks and feels great once installed. Sliders were loose but the pads were so tight in them even with lube I had to push/work them in. So that being said they did not slide. I would have had to grind down the tabs, which I didn't want to do. Eventually I made them fit. Wear gloves with these semi metallic pads as the will leave slivers in your skin. A great product so far, no rattles or stickiness....recommended for volts and other like gm vehicles.
Quality product from a quality supplier! I have ordered plenty of parts online in my life. This is the first time ever I had an actual person connect with me and confirm that the parts I was ordering were indeed the correct ones I needed for my vehicle. Was actually very impressed that they didn't want to ship until it was all verified to be correct, top notch! Will definitely be ordering through them for any of my future parts needs!
After a couple months these "coated" rotors developed so much rust in the drilled holes and slots. Not really impressed with the quality but they do stop the car I guess.
The service great and the parts are also great the people contacts you if you made wrong selection of the wrong part and that's what the people need less returns and les hassle every body wins thumps up
The shipping is super fast, the rotors and pads are packaged well, the customer service is helpful, everything looks good. Parts Pioneer is doing a great job.
Parts came on time and were correct. I have the brakes installed already and they are working good. Sway bar end links not installed yet, but appear good.
I love PartsPioneer. The rear-wheel Positive Plus pads and Genius rotors fit perfectly on my 2019 Subaru Forester. Excellent quality at a fair price. Highly recommended.
Terrible customer service and misleading shipping information. I ordered brake calipers to be delivered to Newfoundland. When checking out it said it would arrive by Sept 3rd. When I got my tracking code it has changed to Sept 8th and said it was shipped from Alberta. I purchased these parts from an Ontario company! I had to reschedule my service appointment to the 9th. They still have not arrived so I have to purchase the calipers locally for twice the price and Parts Pioneer only offered me a 15% refund. No option to return them without having to pay the shipping myself. Unbelievable! Do not trust their shipping times if the parts are for a time sensitive repair.
Thanks for catching an error in my order and righting it for me, complete with email to say so! This … is what customer service head and shoulders above, looks like !! Well done all !!
