How many spark plugs do I need to replace in my 2002 Benz E320?Your car has a V6 engine with two spark plugs per Cylinder. And yes you do need to replace all twelve of them. The plugs i use are N.G.Ks and have never had any problems with them in the 15 years we have used them. Leave your Spark plug wires or H.T leads well alone. One word of warning i have swapped dozens of these plugs in the V6s and none of the H.T leads have come off easily. It is very easy to pull the lead from the plug cap so be very very careful.How many spark plugs do I need to replace in my 2002 Benz E320?12 of them.How many spark plugs do I need to replace in my 2002 Benz E320?The Bosch Platinums are inferior to the NGK Iridiums(I run them BOTH in my MBZ and 911).



The best prices I found for the NGK Iridiums are Autozone for $5.99 each, instead of Kraegen which wanted $11.99 each, so it pays to shop around. They last a LONG time, so when installed, it should be 75-100K before you need new plugs again.



CARQUEST is also an excellent source for FACTORY parts, such as Zimmerman rotors, etc.



Unless your car has 150K plus miles on it, don't touch the factory wires, and NEVER buy aftermarkets wires for a MBZ.
