Buying advice

When selecting spark plug looms and accessories, prioritize heat resistance if you have aftermarket headers or a tight engine bay to prevent wire melting. Ensure the wire resistance is compatible with your ignition system, as high-performance wires with very low resistance can sometimes interfere with sensitive electronics. Always measure the length you need carefully to avoid buying universal sets that require excessive cutting or splicing, and look for locking mechanisms on the boots to ensure a secure connection that resists vibration.
