Infinity i35 has generic motor q35 which is shared amongst other manufacturers, including Nissan, Infinity, Japanese family engines, etc. If these plugs fit Nissan, they will fit 3.5L Infinity motor.

I have no idea, they worked out fine on my 2007 japanese made Toyota Camry. Sorry

The wire colors are correct, but the wire length is around 10" and no 4 pin plug. It's a universal fitment meaning you'd cut off your existing plug, strip the wires about 1/4" and use the supplied but connectors and heat shrink tubing for insulation against the elements. I put this is my Lexus IS300 about 3 months ago and haven't seen the check engine light since. Good luck!

I had to return this tool because it did not fit my vehicle. I have a e92 (2007 328XI Coupe). I ended up using a standard spark plug socket. I believe this tool is only for the turbo engines - 335 and M3.

Without knowing the year or engine, I cannot tell you for sure. A 2007 INFINITI G35 3.5L V6 F/I uses a different filter a HP-1008. I recommend checking the K&N website ( http://www.knfilters.com/ ) search by vehicle function.

I installed them on a 2003 745i. At first, they appeared to need the included adapter however after applying some pressure and dielectric grease it fit perfectly. Unfortunately Sylvania.com doesn't offer much help either which leaves 2 options; call the bmw dealer and ask if both cars Angel eye bulbs are the same, if that doesn't help visit the Bmw club forums online and ask the Bmw owners all over the world via posting a forum. I hope I've helped you in your quest.

I have an E350. They fit my car like a glove , easy to install, and a great price. If you check vehicle guide, and it says it fits, should be OK.

I can't say for sure. When I put them in my 2002 they literally started smoking and blew the fuse. I'd look elsewhere.

ABSOLUTELY NOT! These plugs are specific to your year, make, model and engine. Be sure that you order the right ones.

They will, you need an 02 plug and throw the gaskets that come with these headers away and buy a good set. Great headers! Garbage Gaskets!

all iridium spark plugs are pre-gapped. do not try to gap them. they will get damaged !!

Be sure to verify the engine code "VQ35DE". This flywheel fits the following... 2003 - 2007 Infiniti G35 (3.5L V6 DOHC; VQ35DE) Also realize the photo on Amazon is not the actual item. The actual dual mass flywheel will appear thicker. You can see the actual photo from LUK's website here... http://catalog.schaeffler-aftermarket.us/images/catalogPhotos/2921/DMF067_1.jpg

Should fit. The ones I replaced out of my 2003 G35S were a bit larger (by 1/2 inch). The new ones fit perfecrly.

I bought these and they fit my 1999, they probably do fit your I4, Amazon offers a parts check fit feature for your specific year and engine that I would use to make sure.

Yes, it will fit those model years. I installed it in a 2003 G35 Coupe with a manual, good install but requires slight modification if you have a Stock Infiniti Nav system as I did, but even with the Nav this unit still came together great

It may, since Infinitis are part of the Nissan Corp. You can search it in Amazon.com and find whether it will fit the year and model of your vehicle. That's what I did for my 2008 Nissan Altima
