Infiniti G35 Catalytic Converter Replacements
Shop Infiniti G35 catalytic converter replacements at A-Premium for a failed catalyst or damaged converter assembly. The catalyst treats harmful gases before they leave the exhaust. Begin with the model year and whether you drive a coupe or sedan. This matters especially for 2007: the G35 coupe used the VQ35DE engine, while the sedan used the VQ35HR. Both are 3.5-liter V6 engines, so displacement alone does not identify the correct converter application.
Once the vehicle application is identified, choose the converter for the diagnosed side or the work required on both sides. The G35 collection includes individual left- and right-side parts as well as driver-and-passenger pairs. Match the specific body, engine and drivetrain application before selecting a package, and choose an emissions specification appropriate for the vehicle and where it is registered. A catalyst-efficiency code should be diagnosed before deciding which unit to replace.
Why Choose Infiniti G35 Catalytic Converters from A-Premium?
Match the G35 engine and body application first, even when two A-Premium converters have the same flange bolt count.
- Match the Parts to a One- or Two-Side Repair: The G35 collection includes individual side-specific converters and two-piece driver-and-passenger packages for specified applications. A single-side repair can retain a sound, separately serviceable converter. When both sides need replacement, a matching pair covers both positions in one package.
- Use Matching Flanged Connections: The listed G35 pairs include assemblies with three-bolt welded inlet flanges and two-bolt welded outlet flanges. On the corresponding original exhaust layout, the converters join the existing connections rather than requiring the fabrication needed for a universal body.
- Restore Exhaust Treatment: Catalyst surfaces promote reactions that turn harmful exhaust gases into less harmful substances. Replacing an ineffective G35 catalyst renews that treatment function.
FAQs About Infiniti G35 Catalytic Converters
Can a clogged Infiniti G35 catalytic converter be cleared without replacement?
Find the cause of the restriction before choosing a remedy. A melted or collapsed catalyst has physical damage that a cleaning additive cannot rebuild. If diagnosis confirms that damage, replace the affected converter and correct any underlying fault found during diagnosis. A catalyst-efficiency code by itself does not prove a blockage.
Does a G35 bank-related fault code identify the driver-side converter?
A bank number is not a universal driver-side label. Use the service information for the installed G35 engine to locate the bank identified during diagnosis, then match that physical location to the part diagram. This prevents ordering the opposite-side converter.
What affects the cost of Infiniti G35 catalytic converter replacement?
The number of converters being replaced and the installation work affect the total. Request a quote for the side or sides that need replacement, including labor, seals and any sensor repairs. Compare a single-converter quote with another single-side repair, and a pair with the same two-side scope. If the G35 has an aftermarket exhaust, include any adaptation of the connections in the estimate.
Do I need new oxygen sensors with my G35 catalytic converters?
Serviceable sensors can be reused if removal leaves them undamaged and the repair procedure permits reuse. Replace a sensor for its own fault or damage to its threads or wiring. Determine those needs separately from choosing a single converter or a paired package.
