    Default Need advice - Spark Plug Connectors & quality/price

    Okay, so i've finally tracked down my rough idle. No vacuum leaks, cleaned throttle body, ran Jectron and the valve cleaner through 3x each. All the above has incremtally improved things, but still that intermittent choppy idle. So I pull the coil covers off my M60 while the car is in drive with the A/C on and sure enough, I hear spark arcing in perfect timing with the rough idle. So i pull the coils and the ends of the connectors are trash.

    No problem. My question to you is what to replace them with. I found them at Autohaus Arizona (Bremi) for $5.66 each. While most other places want upward of $14 each (OEM: Beru or Germany). So what's the quality difference? Anyone use these Bremi's? Do they suck, hence the difference in price? I'd much rather shell out $45 for a set of 8 rather than $115, but I'll pay the extra money to avoid issues if that's the case.

    Your feedback is appreciated!!

    Thanks,

    John

    bremi is supposed to only go on bremi. remove your valve cover and determine what type of coil packs you have. if they are bremi, you've found yourself an excellent deal. if they are bosch, you should buy bosch from a source that carries them, such as bma. bosch connectors have a lower resistance to work with bosch coils, bremi have higher 1.8 ohm resistances.

    Thanks for the info guys!

    Wow, I guess all the planets lined up or something. Just checked, I have Bremi coils so these will work just fine. Based on Josh's comment then, I guess these are oem replacement for me, right?

    All I know is that I have 8 headed my way for $45.28 and shipping. If it will help anyone else:

    No oil Jeff, she bone dry in there. Say, was just reading a previous post of yours touting your prowess at finding the cheapest deal on spark plugs. You pointed us to carparts.com for F7LDCR's @ $1.99 each back in November. Now they're up to $3.99 ea. on that site.

    Can you beat $3.99? Let's see "the man" in action....

    Update:

    Received the Bremi connector boots and installed them this past weekend. They're great quality and the updated versions with a better design for the plug end. Better fit.

    Used Dielectric grease to prevent them sticking to the plugs and to further deter spark leakage. Easy job. Took about 30 minutes total from hood up to hood closed.

    Immediatly noticed a better idle. But still an intermittent misfire. MUCH less than before, but in retrospect, I should have replaced the plugs while I was there. But this is good in that I can see what each "job" does to improve my idle quality.

    Here's the rub though. Definately improved power at all rpms. Very happy about that, BUT man, I can smell a bunch of hydrocarbons in my exhaust now. Don't know if the DME was compensating for the misfiring before with a richer fuel mix or something, but it's concerning me.

    So, is it time for a Shogun Reboot? Or should I do the plugs first?

    Thanks!

    I was about to buy the Beru and decided to search. Which do they work with?

    do plugs first, im a Denso iridium fanboy, get those!

    if your exhaust smells of fuel, your O2 sensors may be reporting incorrectly and need to be replaced, you could have a stuck or leaky injector, or the fuel just isnt combusting correctly (fouled injector, or bad coil)
