Spark Plugs?

Postby porksoda » Wed Jan 28, 2015 10:27 pm

I know this question has probably been asked a hundred times but I am wondering what kind of Spark Plugs everyone is running or has experience with for our trucks.
I went to the parts store and I was asked many questions about what preference I wanted, but I am totally unsure on what works best for our trucks.

They offered me Iridiums, Double Platinum, Platinum, and Copper styles of plugs.
And there where a lot of brands that were offered.

Thanks for any advice!

SMJ has posted many times on this and has much insight into the different plugs out there. Specifically, the recommendation is to stick with NGK plugs, which are the OE installed part. However, from there, there are several options at varying cost levels.

PLFR5A11 are what your truck came with from the factory (its an 06, right?). Rockauto has them for $12.09 each

08+ V6s came with ***DILFR5A11*** (corrected), are $18.44 each from RockAuto.

Per SMJ's message back then, either will work just fine.

Personally I would stick with NGK I have used them many times on many differs applications and they always run great.

I bought Nissan OEM (NKG) plugs on ebay for a reasonable price. Changed them at 100k and didn't notice any difference in performance/economy. Seems like a good plug!

Same plug that is in my car.

I went with the LFR5AIX11 for my Maxima, going to change them this week (2nd set of these). I'll stand by them. I paid 38$ shipped for 6 of them.

05-07 Pathfinders/Xterras/Frontiers, which all had the VQ40DE, came with NGK #PLFR5A-11 (stock #6240) Laser Platinum spark plugs.

08-12 Pathfinders/Xterras/Frontiers with the VQ40DE came with NGK #DILFR5A11 (Stock #93759) OE Laser Iridium spark plugs.

*NOTE: They never came with #LFR5AIX-11's, which are NGK Iridium IX plugs. These will work, but they are an economy Iridium plug and are only recommended for 60,000 mile intervals. The #PLFR5A-11 Laser Platinums, which like the OE Iridiums are rated at 105,000 mile intervals, will work just fine in place of the OE Iridiums and are much less expensive. Iridium is a denser material than Platinum and is a better material for spark plugs, but the amount of performance difference between the two you will notice is negligible if not non-existent.

08-12 Pathfinders with the VK56DE V8, from what I've been told, also come with the NGK #DILFR5A11 (Stock #93759) OE Laser Iridium spark plugs. What I find interesting is the NGK's site calls for #DILFR5C11 (Stock #5443) OE Laser Iridiums (Rockauto.com lists the #DILFR5A11). I think either would work fine; the difference is in the firing end construction. According to the Nissan catalog, the DILFR5A11 has a "special design" firing end, whatever that means, and the DILFR5C11 has a "low angle ground electrode."

Rockauto.com is a good place for spark plugs. I usually get the Laser Platinums at AdvanceAutoParts.com. I order them online for store pick-up using discount code "TRT30," which gives you 30% off, and they end up costing $9.99/plug + tax. It usually works out a little cheaper than Rockauto because of the shipping cost. As far as the OE Iridiums, I have a hard time finding them in stock at the local Advance Auto Parts stores.
