Choose Walker Products because:

Walker Products Distributor Caps are OE Replacement components designed to restore proper spark distribution in vehicles equipped with conventional distributor-based ignition systems. The distributor cap directs high-voltage current from the ignition coil to the appropriate spark plug via the rotor and internal terminals. Over time, distributor caps can suffer from carbon tracking, cracking, or corrosion—leading to misfires, hard starting, and drivability issues. Walker distributor caps are engineered to meet OE specifications for terminal layout, material strength, and electrical conductivity, ensuring consistent spark delivery and reliable engine operation. Each unit is manufactured using high-dielectric, heat-resistant materials that withstand high voltage, engine heat, and mechanical stress. Designed for an exact OE fit, these caps install easily into the original distributor housing and maintain a secure connection with the rotor and ignition wires. Whether part of a tune-up or ignition system repair, Walker Distributor Caps help restore precise ignition timing, improve fuel efficiency, and reduce emissions in classic and late-model applications.

Characteristics include:

Exact OE Fit: Designed for 100% fit with original distributor housings—ensuring a secure seal and reliable contact points.
OE Replacement Quality: Built to meet OE specs for terminal alignment, dielectric strength, and conductive path precision.
Directs High-Voltage Spark: Routes ignition coil output to the correct cylinder to ensure proper firing order and engine performance.
Restores Ignition Timing & Spark Delivery: Helps resolve misfires, hard starts, and poor performance caused by cracked or worn caps.
Heat-Resistant Materials: Constructed with high-dielectric compounds to withstand high voltage, thermal cycling, and engine vibration.

Parts were well packaged, came with all hardware needed for clips, anti rattle clips, as well as mounting hardware. I drove the car to have the car relearn piston positioning, and these are much more grippy than factory honda/acura pads and rotors, so I am really happy with them. I am surprised it only took 3 days for them to arrive after ordering them from Calgary to sw ontario. I have already recommended part pioneer and this brand of pads and rotors to my friends.
