🔥 NGK 3403 G-Power Platinum Alloy Spark Plug TR55GP - Set of 8, Brand New Review

These candles arrived quickly and are in perfect condition. I can't wait to turn on all my other parts so I can tune in and get all my lost power back. *UPDATE* Installed the new MSD coil-on plugs in my 2000 Mustang GT on the same day and am very satisfied. I had no idea how much power was gone since the day I bought the car and now I have it, and even a little bit. Great item, great price, great seller!

What a time saver! It's always good to have spark plugs with preset gaps to match the vehicle's specs! I didn't have to adjust the 8 plugs I bought at all - I just made sure the gap on each one was correct and plugged them all in without worrying about the gaps; exactly on all 8 plugs. This is the first time I've received pre-gap plugs...and I didn't know what they were when I ordered them - I have NGK to thank for that! It's fine if you only have a four cylinder engine, you know how to plug in

I just installed them on a 1997 El Dorado - misfire engine code and previous O2 sensor codes. The power and response is amazing - jumped from 16mpg city to almost 21 - haven't driven it on the highway yet but I'm sure the MPG will be +5. No more rough idle times or computer crashes. Great price - this is my first use of NGK and I'm sold. Was a Bosch user and champion. no longer. Update on previous reviews - they performed better than expected. I've seen my highway mpg go up to 26mpg which is…

I've been a fan of NGK for a long time, Denso too. But I chose NGK Platinum for my (new to me) 08 f-150. It's a 4.6 V8 so the plugs are normal but the larger V8 has crappy plugs with a 3 piece design. So glad it isn't. If you make spark plugs on this car and then change coil packs, you can find them cheap here. Since you're going to be climbing into the engine bay and spending some time there, just replace them. And when it's done what difference does it make, I can't confirm the gas mileage…

I've been using NGK spark plugs for years. I've used them in every possible random machine over the years and never had any problems. I took this set for 06 F150 4.6. The previous owner couldn't seem to decide which plugs he needed and installed 4 different types. All old candles had different gaps and ages. Of course that made a big difference. The pre-gap on each plug was nearly accurate for 7 plugs. One of them only needed minimal adjustment and was actually fine. I added some antiseptic…

Installed on a 2004 Monte Carlo with a naturally aspirated 3800 Series II V6 transversely mounted engine and driven approximately 135,000 miles. Due to the design of the engine in this car, you must remove the two "dog bone" front engine mounts and use a ratchet strap attached to the rear anchorage and front cross member to pull the engine forward to allow enough clearance for the engine Gain access to the rear cylinder bank (#2, 4, and 6). ALWAYS BLOCK THE WHEELS AND SHIFT THE VEHICLE INTO…

Used these spark plugs to tune my 1996 Lincoln Town Car. I had very severe misfires between 35 and 55 mph which made the car jerky. To be honest it was like a transmission error. I did a little research and found that this feeling could be caused by a misfire. Before fitting these spark plugs I removed the existing ones and found them to be in very poor condition. After replacing them with these plugs, it FIRED immediately when I turned the key, unlike before when it was hard to turn. I…
