What kind of spark plugs does Lavida use?

[JuneDella]

The 1.6L engine of Volkswagen Lavida originally uses Bosch spark plugs with the model number F7HER2. Composition of spark plugs: Spark plugs mainly consist of terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. Types of spark plugs: Main types of spark plugs include: standard spark plugs, projected insulator spark plugs, electrode spark plugs, seat spark plugs, pole spark plugs, and surface gap spark plugs. Replacement interval for spark plugs: Under normal maintenance conditions, replacement is recommended every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it's advisable to follow the user manual. Platinum spark plugs should be replaced every 40,000 km, ordinary nickel alloy spark plugs every 20,000 km, and iridium spark plugs every 60,000 to 80,000 km.

Last time when my Lavida was serviced, I specifically researched spark plugs. The original ones are standard nickel alloy, but switching to double platinum ones is actually more cost-effective, with a lifespan of up to 60,000 km. For the 1.6L naturally aspirated engine, Bosch FR7HPP22W will do, while the 1.4T turbocharged engine must use NGK 94833, which is iridium platinum. The key is to check your engine model - EA211 and EA111 use different types. When removing the old spark plugs, note down the thread diameter and heat range parameters, as buying the wrong model may cause ignition issues. I finally chose Denso's double iridium ones, and cold starts are indeed much faster now, with fuel consumption dropping by about 0.5L/100km.

When replacing spark plugs for Lavida, focus on three key aspects: material, heat range, and gap. For older 1.6L models, the nickel-alloy Bosch Y7LER02 is perfectly adequate, costing just tens of yuan per piece. However, turbocharged (T) engines should upgrade to platinum or iridium materials. Selecting a heat range between 6-7 is safest, with a gap of 0.7-0.9mm being acceptable. I once helped a colleague replace spark plugs on a Lavida Plus and discovered that the new 1.5L engine actually requires special long-thread models – we almost bought the wrong ones. Recommendation: When removing old spark plugs, use a vernier caliper to measure electrode length, as roadside mechanics often install them incorrectly based on experience alone.
