"quality of product great price and fast shipping!!!" posted by: ray on June 25, 2014

"This converter appears to be well built, and solved my P0240 (inefficient catalytic converter) code problem immediately. Can't beat the price and free, quick (3 days) shipping. If your existing front pipe is in good shape, this converter is well worth the hassle of adapting it to fit." posted by: Pistole on September 11, 2010 view all 5 reviews

A driver's responsibility is not only limited to the proper observation of traffic rules and regulations. It is part of every driver's duty to keep his vehicle's emissions free from harmful toxins. For Mazda 626 owners, processing and emitting less harmful gasses is just a piece of cake. Equipped with a first-rate catalytic converter, the Mazda 626 will always be eco-friendly. But just like any other part of your road surfer, the Mazda 626 catalytic converter is not damage-proof. Cracks and other forms of damages due to rear-end collisions and several years of non-stop and painstaking gas decontaminations will eventually take its toll on your cat converter. Of course, you can't allow your vehicle to surf the streets without a proper-functioning catalytic converter. Don't let your gorgeous Mazda 626 turn into a big-time toxin machine. Before you get yourself into some serious engine or police trouble, get rid of your old and useless stock and grab yourself a brand-new Mazda 626 catalytic converter.

Frequently Asked Questions

Ask APW
  • Can a faulty EGR Valve cause catalytic converter failure in Mazda 626 models?
    Answer: Yes. The exhaust gas recirculation (EGR) valve is an important component of the Mazda 626's exhaust system. It is engineered to reduce combustion temperature by re-circulating the exhaust gases into the intake. Should it fail to do its job, combustion temperature will skyrocket. This will eventually cause the slow meltdown of certain catalytic converter components. Faulty EGR valve, plus a lean fuel to air ratio or poor ignition timing, can boost substrate meltdown in the catalytic converter.
  • Can engine backfires in Mazda 626 models be caused by a damaged catalytic converter
    Answer: Yes. In fact, most Mazda 626 models experience engine backfires due to a catalytic converter breakdown. If a Mazda 626's cat converter is not in excellent condition, it will produce incorrect engine readings. This will result to inaccurate engine system timing. The aftermath? An engine backfire or after fire.
  • Oxidation or three-way? Which catalytic converter type is better for a Mazda 626?
    Answer: Majority of the available catalytic converter replacements for Mazda 626 models are of the three-way catalyst type. Three-way catalytic converters are preferred by most Mazda 626 owners because of their oxidation/reduction capabilities. Like the oxidation type of catalytic converter, three-way cats process hydrocarbons and carbon monoxide. The cat converter's substrate component boosts oxidation to convert these harmful gases into carbon dioxide or water vapor, which are obviously less harmful. What makes the three-way converter a better choice is its ability to lower the levels of oxides of nitrogen. Some three-way cats also have an added air injection tube, which furthers the chemical reaction to boost oxidation.
  • What can 'running rich' do to a Mazda 626 catalytic converter?
    Answer: Running rich is detrimental to a Mazda catalytic converter because it often results to overheating. Overheating is one of the main causes of cat converter failure in most Mazda 626 models, apart from poor tuning, faulty oxygen sensor, and other damaged exhaust system components.
