• Where can I find user manuals for DENSO auto parts?

  Many DENSO automotive parts are Original Equipment (OE) components and do not come with separate user manuals. For installation and specifications, refer to your vehicle's service manual. Aftermarket parts like spark plugs may have instructions on the packaging.

• Кантип мен file a warranty claim for a DENSO product?

  DENSO advises consumers to contact the retailer, dealer, or distributor where the product was originally purchased to initiate a warranty claim, as they generally do not handle direct consumer claims.

• What is the correct gap for DENSO spark plugs?

  DENSO spark plugs are often pre-gapped, but it is recommended to check the gap against your vehicle manufacturer's specifications before installation. Do not alter the gap for Iridium Power, Iridium TT, or Iridium Racing plugs as this may damage the electrode.

• Where can I download manuals for DENSO WAVE scanners?

  Manuals and software for DENSO WAVE products, such as barcode scanners and handy terminals, can be downloaded from the official DENSO WAVE website under the support or download section.
