Best Ignition Coil For Lexus GS350 FAQ

What are the common symptoms of a failing ignition coil in a Lexus GS350?

The most common symptoms include engine misfiring (especially under load or acceleration), rough idling, reduced fuel economy, and the illumination of the Check Engine Light (CEL). Often, the OBD-II code P0300 (Random Misfire) or a specific cylinder misfire code (P0301-P0306) will confirm a faulty coil.

Do I need to replace all six coils at once on my V6 GS350?

While you can technically replace only the failed coil, it is highly recommended to replace all six at the same time. Coils typically wear out at similar rates. Replacing only one often leads to another failure shortly after, requiring you to repeat the labor (especially for the coils located under the intake manifold, which are difficult to access).

Is there a difference between the UF-487 and UF-796 coil packs for the GS350?

Yes, there is a difference. The UF-487 is the common reference number for many earlier 3.5L 2GR-FSE engines in the GS350 (2007-2011). The UF-796 (OE# 90919-02273) is a newer design found on later generation GS and IS models. Always cross-reference the OE number stamped on your original coil or consult your vehicle manual before ordering replacement parts.

How difficult is it to perform an ignition coil replacement on the Lexus GS350 V6 (2GR-FSE)?

The difficulty is moderate. The three front coils are relatively easy to access. However, the three rear coils require removing the intake manifold (plenum) to gain access. This process requires patience, proper tools, and replacing the intake manifold gaskets (LSI keywords: plenum gasket replacement) to ensure no vacuum leaks occur upon reassembly.

What causes ignition coils to fail prematurely in the GS350?

Common causes include excessive heat exposure (which degrades the internal epoxy and wiring insulation), voltage spikes from a faulty alternator or battery, and most commonly, worn-out spark plugs. Old spark plugs require higher voltage to jump the gap, causing the coil to work harder and ultimately overheat and fail.

Are aftermarket ignition coils reliable, or should I stick to OEM?

Modern aftermarket options like A-Premium, ENA, and BDFHYK are highly reliable and cost-effective. While OEM coils are guaranteed to fit and function perfectly, high-quality aftermarket coils often use similar materials and manufacturing processes (sometimes even better, utilizing enhanced heat-resistant plastics) and offer substantial cost savings compared to genuine Lexus parts. Choosing the best ignition coil for lexus gs350 often comes down to balancing quality specs and budget.
