JSGS30004

Hello all, i had some parts changed by a local mechanic and was wondering if this was too much. I certainly am shocked at the prices. $450 for spark plugs and wire set; $350 for ignition coil. This includes labor but i believe i was overcharged. I under this business and a profit needs to be made but still. Any insight is helpful. Thanks!

A quality NGK wire set is around $29. Good quality NGK or Denso spark plugs are around $5ish a plug and you need 6:

If you really needed a ignition coil you have 3 total and cost around $72 a piece for a Denso replacement but I would inspect your coil plugs from the engine wiring harness or swap coils around to see if you really have a problem or not:

My 2 cents I would avoid that place and do the job yourself if you have some basic sockets and hand tools.

It's a fair amount of work to change plugs / plug wires / coils on a GS 300. Because of that, it uses long life spark plugs, which cost more than $5. Given the amount of labor, $450 total for 6 plugs, plug wires and labor is not too outlandish.

However, once the labor for the plugs and wires is done there should be very little extra labor to replace the coil. What's the parts vs. labor breakdown?

Um, no it isn't. It takes 15min at most to pull the intake tube and throttle body to expose the plugs/coils. OP got ripped off. I did all three plug wires, new boots on the coils, all 6 plugs (NGK Iridium IX), and a new throttle body gasket for $100.93 in parts, doing the work myself. If you add one new coil into that, you're still under $200 plus labor. There's no way labor should be $600 to equate the $800 the OP paid.

On the GS4 (for comparison only...), believe we paid about $110 for all 8 plugs, pre-gapped, from Toyota (same part number, we can visit them during lunch, Lexus dealership is about 30min away). The coil-over-plugs are expensive, budget $80-$100 per, from local auto-parts... and there's (8) of them... afraid to ask what Lexus would charge for them.

$450 for 6 plugs and a wire set installed, does seem a bit high.

Was it one or all coils that were replaced? I'd verify that because if all were replaced, the price is much more reasonable. Even if that's not the case.. are you forgetting about the diagnostic price/labor? Surely he had to find out what your issue was. Maybe even put the intake back together a few times to swap things around.

I suspect it might take more than 15 minutes worth of labor to diagnose, replace and reassemble everything. I don't expect to get the same prices for parts at a mechanic that I can get shopping around online.

I agree and said as much. That's why I asked for more detail on the parts / labor split.

Shop probably just charged what the book called for.

I'm used to changing plugs and wires on my 12 cylinder BMW, which is a 7 hour job any way you cut it. I changed plugs and coil packs in my GS3 last week, start to finish took me 2 hours. Now that I've done it once I will cut that time in half next time I do it. There are plenty of helpful how to threads here. I spent around 150.

natman

I wouldn't be surprised. However, charging what the book called for when 90% of the work is already done on another job taking place at the same time is double dipping. I don't know for sure if that's what's happening here, but it looks as if it's possible.

Common with oil-pump gaskets and timing belts... once it's all apart, changing the oil pump gasket takes about 15min.

Bought my coil packs from Ebay had no problems!! For like $40
