Key Features

  • Direct ignition coil boot for coil-on-plug setups

  • Spring included with the coil boot
  • Built for vehicles using direct ignition
  • Cross-references Standard Ignition SPP198E applications with OE-style replacement numbers

Detailed Description

SPP198E is a replacement coil boot for direct ignition systems where the boot bridges the ignition coil and spark plug. It is a fitment-based solution for select Cadillac SRX, STS, XLR, DeVille, and Seville models, plus Pontiac Bonneville applications. This part cross-references 99-230 and SPB261 for the same application. If you are servicing a Cadillac SRX ignition misfire concern or replacing a worn coil boot on a Pontiac Bonneville, Standard Ignition SPP198E provides the correct direct-ignition interface.

What It Helps Address

  • Ignition misfire caused by a deteriorated coil boot
  • Weak spark transfer between coil and spark plug
  • Carbon tracking at the boot surface
  • Cracked, hardened, or heat-damaged boot material
  • Intermittent ignition performance on direct ignition systems

Installation Notes and Tips

Install the boot directly between the coil and spark plug on the listed applications. Inspect the spark plug well, coil tower, and plug condition before installation, and replace any damaged ignition components found during service. Verify vehicle fitment by year, make, and model before ordering SPP198E.

Quality Assurance

Standard Ignition supplies replacement ignition hardware for direct ignition service applications. SPP198E is engineered for the listed Cadillac and Pontiac fitments and follows the original design used on those vehicles.
