When are people replacing their spark plug wires. How long do the OEMs last. Mine are 6 years old now. Do they need replacing and with what? OEM, after market, EvoSport?

 

I changed mine with factory OEM wires at 60K, figured it couldn't hurt.

 

Seems a lot of people really like their EvoSport plug wires. I ran a set for about two years until they cracked and threw CELs. The codes were misfire. I switched back to OEMs.

 

how much do the oem ones sell for?

 

About $700 for all 16

 

$480 at MB Sugar Land.

 

if not abused will last the life of the car.
Properly removed at plug changes and short of setting them on fire they will outlast the engine.
oem are $160 a set even if you did abuse them
$480-700 is sheer folly besides being a waste of money

 

Do plugs at 25K, wires at 50K to be safe...

 

Well if there is no advantage to after market wires then OEM it is.
ohlord, where do you find the OEMs for $160.00?

 

$160???? I called the mercedes dealership and they said 2 of them are $52, 12 of them are $41, and 2 of them are $36.

 

Wow the dealership where I'm at is really trying to screw me over!!! Is that for 16 or 8???

metal boots oe full set.
although you don't need them unless you yanked the old wires off by their boots.


25k for plugs and 50k for wires ????? somebody is sorely uninformed

 

Here's another place to try. They have a few different brands, Beru, Karyln/STI, and Bosch.

europartsdirect.com

 

A full set of 16 will run you $189.88 from europartsdirect.com. Thats pretty cheap!
Has anyone bought a set of Bosch wires from this company? I want to confirm that the Bosch are actual OEM, and not OEM "like".

I bought a set of wires from parts.com and they ended up being aftermarket which didn't fit properly (some wires were too short).
Hoping to avoid the same scenario.

Thanks

 

I already purchases a set from here and they are genuine Bosch wires. This place was referred to me by other reputable members here on the board. From my understanding our cars came with different wires. It varied from Bosch to beru, from what I was told.

BTW...the set I bought was Bosch and with no problems.

 

Thanks Alan, I'll go ahead and place my order.

 

Correct, there is no recommended interval, nor would I replace them if they were not causing misfires. As stated they will last quite a long time if properly removed at each plug service.

 

I was wondering which set are the Bosch ones on europartsdirect. I see OPparts, Karlyn, and Beru. They're priced at $131, $187, and $168. Any help would be appreciated, thanks!

P.S. What spark plugs would you guys recommend?

 

25K plugs and 50K wires ? you should extend double !

 

Rock Auto has them for $176.79 (BOSCH Part # 09850) and if memory serves, you can find a 10% discount code pretty easy and apply it. I did this a few months back.

 

I might be placing my order with them as well. Any other reputable places for the OEM wires?
