Has anyone ever used the lifetime warranty of Bosch ignition wire setfrom Autozone. A little more expensive than online, but free replacements?? A set for my 4.5L 117.985 is $100.

One of the pro techs who helps out here has mentioned that Bosch quality is not created equal. They make good(sometimes) and not so good.

Guess which one ends up at AZ?

AZ's starters and alternators are pure garbage. Yes they have a lifetime warranty, but what good is it if you have to pull and take back very 6 weeks.

I wouldn't believe that their Bosch wires are any better than any of the rest of their junk elect. parts.

There are a lot of web sellers that can provide Beru wires which some believe are better than Bosch.

I bought a set of Beru's(OEM wires) from these people for less than AZ wants for the Bosch wires mentioned at the start of this thread.

But for someone who wants to change a set every 3 years, that is not a bad deal though......I have Beru on the car know but some of the ends are corroded.. while looking for a replacement set I ran across the feature of lifetime warranty. I am not a fan of AZ but the warranty is intriguing......that's the reason for the post to see if anyone has tried their Bosch wires....

go to advance auto part stores.they carry exacts, autolites and ac delco with lifetime replacement.

And I'll bet those wires are original. Not bad for 25 yrs. Again, Beru is OEM - better wires.

I bought a rather expensive ($150) set, can't remember the brand, for my 560sl mail order and I was very disappointed with the tailoring. The wires were of significantly different length from my (original, 18 year old) Bosch set. I researched this some time ago and in addition to the tailoring issue, some mfr's don't even angle the appropriate connectors/heat shields like the originals - they are straight. How much DO you have to pay for a good set (short of dealer robbery)?

I paid $118.00 for a set of OEM Beru's from the site mentioned in an earlier thread.

The wires on the car were Beru-original. M.B.DOC has mentioned in previous threads that Beru is OEM; Bosch is not.

I was in an MB dealership the other day and asked to see a new set of wires for my MB. Dealer wanted $189.xx for Bosch wires. The quality didn't look anywhere near as good as the Beru's I bought for $118.00.

Hi guys 2 years ago I needed a tune up on my 86 300e. So with my past experience of hot rodding I did a bit of customization.I purchased a set of 8mm Taylor spiro pros the universal set.Along with adding an Msd Super coil and AC Delco Irridium rapid fire plugs I havent had any problems.
The car starts better and runs alot smoother than the bosch set.
Also it was alot cheaper going this route.
Wires :$90.00 CAD
Plugs:$10.00 CAD each
MSD Blaster SS Coil:$90.00 CAD

I didnt change the cap and rotor yet due to the fact every fall and spring I polish the contacts using a dremel with a fine wire wheel.(makes it last longer and causes great conductivity)

I have one experience with Bosch lifetime wire sets. This was with my 91 Tracer that ran a stock high energy ignition system. I had to claim the warranty twice because the wires couldn't last. This was all before the car hit 60K.

It's not just the corrosion that reduces conductivity, but also wear of the cap and rotor. When the gap between rotor and distributor starts growing, the energy required to jump this larger gap is taken away from the spark plug.... not a big deal on a healthy ignition system, but considering the great lengths people go to increase the spark energy at the spark plug, this merits consideration.
