Are these too good to be true or are they crap? any guesses?

I am pretty sure my value cover gasgets are getting close (smelly after driving, no visible leak yet but mechanic suspects). So while he's in there I figure doing Coil Packs need to go. I know these should be more like $80 bucks each.

In my experience, cheap coil packs on VH41's can throw misfire codes. I have run them for six years and they do their job, but the check engine light stays on. If you can swing it, get some genuine Hitachi's. If not then it's kind of a dice role. Q's can be picky with electronic items.

Okay thanks, I cannot deal with any Check Engine lights in CA, will not pass smog. So if I find Hitcahi on ebay those are equivalent to the ones I would get from a dealership?

When I looked a long time ago, they were about $110-120 a piece. eBay I would be weary of unless it's a very reputable store as people will sell cheap Chinese stuff as OEM. But do your due diligence and make sure the parts have the correct part number and markings on them. If you are still reticent, then you can also go to the dealership but it's expensive.

If I were buying them, I'd probably go with the $40.79 Hitachi coils from Rock Auto. They're a fairly reputable source. When I purchased a Hitachi alternator for my truck, it was drop shipped directly from Hitachi's facility in KY.

Thanks, I think that will work for me. My local mechanic as talking about $80 bucks each which would really hurt as the labor is a PITA and the valve covers are not going to be cheap either.

I got mine from RA a couple of years ago. They were the real deal, and much cheaper than any other option. Car's been running great since. Replace all 8, pay the price, and enjoy your car running good like it should.

My car runs well now question is when the valve covers finally really leak and thanks much for the RA hint, that will work.

Hey Jeff-
No question replacing all 8 will be preventive, and the Nissan P/N is 22448-3h000. You will recall I had issues almost 5 years ago on the FGY33 about 2000 miles after replacing the vcg, and the NGK PFR5G11's. I scored mine internet from one of the Atlanta area INF dealers, and got them pretty cheap (around $80 per).
But here's my counterpoint: I'm becoming more convinced that the true issue is not the coil pax failing, but the boot seal allowing spark grounding thru the head vs. thru the plug. a little dielectric grease on the plug insulator (but below the terminal) and/or on the inner rim of the coil boot should alleviate the problem. not so much that it gets on the electrical contacts, the idea is just to prevent arcing thru the boot (between boot and plug ceramic insulator).
total digression:
I'm almost complete with a smart coil conversion for the G50.....

Thanks 3Q!!

A lot of good looking Chinese fakes on eBay. Just go to FCP Euro and use their lifetime part guarantee.

All 8 at once because they will all fail sequentially over a short period of time so not worth the time to diagnose each while the car is continuously not running well.

So you have seen them arcing at night?
