great performance
I used these plugs before and have installed them in every truck I have bought. I have noticed increased fuel mileage and increased performance right from the start and they last for more than 50 thousand miles at a time. I average over thirty thousand miles a year on my truck and have gone a couple years between replacement with out any problems or plug failure or drop in performance. I would recommend these plugs to any one who want a good plug with out breaking the bank and want's to to protect their motor.

Are there plugs a good replacement for denso PKH16TT for my 2007 Nissan Frontier SE 6 cyclinder engine
Verified Reply - Steve
Hi Tommy, I'm glad to help you! This Autolite Single Platinum Spark Plug (Part # AP5325) is an exact fit for your 2007 Nissan Frontier SE.
Do I need to use anti seize?
Verified Reply - John the Car-Doc
Hi Shri, I'm glad to assist you! Autolite always recommending to consult the service manual for the vehicle being repaired and using anti-seize only where the original manufacturer recommends it. The nickel coating on this Autolite Single Platinum Spark Plug - Part # AP3924 provided added protection from seizing in aluminum cylinder heads and has made anti-seize less important in spark plug installations. Anti-Seize can alter the tightening torque up to 20%, increasing the risk of breakage. It can also create heat transfer and electrical conductivity concerns.
Is this plug comparable for 93 cadi Seville 4.6 Northstar engine? Noticed the preset gap is . 60 and the gap rating is . 50 for Seville sts, can I reduce the preset gap down to the . 50 rated gap and what do I need to reduce it if it's ok?

No Tony, this Autolite Single Platinum Spark Plug (Part # AP605) does not fit your 1993 Cadillac Seville. We do have an exact spark plug available online for your vehicle and the part number is 3951 and it has a gap size of 1.5mm. Use your spark plug gap tool to adjust the gap. Gently bend the ground electrode in to narrow the gap or bend it out to widen it. Be very careful when making adjustments. Don't bend the electrode more than a few fractions of an inch.
What socket fits this plug?

Hi Misha, happy to help you! Since you didn't mention the specific vehicle, it's hard to tell for sure. To give you the correct information I would need the year, make, model and engine size of the vehicle.
