Did not fit my VW Eurovan


from Panama City, FL

Comments about Denso PW16TT Platinum TT Spark Plug:

I have no idea whether this is a good product, but it is not the correct one. The top also needs to be threaded in order to fit the spark plug wires in a VW Eurovan.

Not for BMW!


from Raleigh, NC

Comments about Denso PW16TT Platinum TT Spark Plug:

This sparkplug can not have the top electrode unscrewed for BMW style wires. You have to have a threaded post, which many other brands have that then slide right into the wire set. Denso - not so.

Comments about Denso PW16TT Platinum TT Spark Plug:

Denso has an excellent spark plug, but they don't have the proper cofiguration for this engine. It uses 14mm by one inch thread reach with a taper seat and a long extended tip. Denso's plug is 3/4" reach with a gasket and standard length tip. I swapped these for Champion Double Platinum at the Advance store. All other plug brands listed by Advance are correct for these Chrysler/Dodge 3.3L and 3.8L engines.

Comments about Denso PW16TT Platinum TT Spark Plug:

these were advertised as applicable to a 1986 E30, but the top does not unscrew, so they won't fit the stock spark plug wires. I had to return them, and buy another brand at a much higher cost. Also lost my online 15% discount!

      what is the most efficient spark plug for saving gas for a dodge intrepid 3.3 1995? oliver

        NGK, Denso, Bosch, Autolite etc are all similar in quality. Normally Spark plugs will not increase gas mileage. However, doing a tune up that includes spark plugs may help improve gas mileage. Typically, the only time you will see increase in gas mileage is when you are fixing a problem with the vehicle such as faulty oxygen sensors or a very dirty air filter. This Denso PW16TT Platinum TT Spark Plug is an ideal fit for your 1995 Dodge Intrepid 3.3.
