Ngk!
Not if you got a few extra wrench extenders, its a little bit of a PITA but much easier than taking off the manifoldi went diamond e3 spark plugs notice a bit faster revving i also installed a wrp i.m.s. same time since u have to take the the intake manifold off to change the plugs
I don't know what year they crossed over, but the first few years of 2nd gen frontiers have platinums, but at some point, like my 2008, they crossed over to iridiums.NGK iridiums worked out great for me, have had no issues with them so far
I do believe stock plugs in the frontys are NGK platinums, so upgrade if you think its worth the extra cheddah, and quite frankly the difference between platinum and iridium in terms of performance and economy will be minimal

X2 NGK! I have tried others but had nothing but problems. Nissans like only NGK's.Ngk!
are you the first owner of your truck cause if they were iridium then i'm pretty sure they weren't oem. all the manuals for 07 only say platinum as the spark plug for our trucks and only give a part number for ngk platinums. in the 08 manuals is where it starts listing part numbers for both platinum and iridium and is when the owners manual starts saying "iridium if so equipped" and its the same for 09Just changed the plugs out in my '07, 45k miles. OEM were NGK Iridiums. Replaced with Bosch Platinum Iridium Fusions... immediately noticed a much smoother idle.
Yup... I ordered her exactly like I wanted, waited 7 weeks and then took delivery the day she came off the truck. MFG date is 11/06. Also, the truck has never been in for warranty work or service. Aside from tires, I'm the only one who has done any wrenching on it. Plugs removed are NGK IR DILFR5A 11. Plugs I installed are Bosch Platinum IR Fusion 4516 and the truck has the smoothest idle I've experienced since day 1.are you the first owner of your truck cause if they were iridium then i'm pretty sure they weren't oem. all the manuals for 07 only say platinum as the spark plug for our trucks and only give a part number for ngk platinums. in the 08 manuals is where it starts listing part numbers for both platinum and iridium and is when the owners manual starts saying "iridium if so equipped" and its the same for 09
