Time to choose the lenses that are right for you
What type of lenses do you need *
We need to get your bifocal or varifocal lenses right, this is how it works *
When you order bifoclas or varifocals we send the frames out to you before making your prescription lenses. You will use the frames to take some important measurments. Next, you'll send back your frames free of charge so that we can produce your perfect prescription lenses. We know some other websites don't do this, but we think it's important to get your glasses right. Any questions, please do contact us!

Add transitions lenses? *
Transition lenses are the lenses that darken in the sunlight and lighten in softer light or the dark. They offer both style and convenience, and can help protect your eyes from UV. Our lenses use genuine Transitions technology.
What colour transitions lenses would you like? *
Would you like to add Blue Shield Technology? *
Blue shield technology includes a blue light blocker to reduce exposure to potentially harmful light from extended periods using electronic devices like phones, tablets and laptops. It also includes an anti-reflective coating to reduce glare and increase the amount of visible light passing through the lens. Plus toughened surfaces reduce the amount and effect of scratches.

Want to add UV 400 protection? *
UV400' refers to UV rays at the top end of the UV spectrum, up to the 400-nanometre wavelength. Sunglasses with this level of protection block an even wider spectrum than the CE and British Standard models, making them the ultimate protection for your eyes.

PRODUCT DESCRIPTION


Weistec's Mclaren Spark Plugs are designed and manufactured for higher power applications. The factory plugs do not handle the M838T or the M840T's high cylinder pressures very well and frequently result in misfire problems, especially on modified vehicles.

The Mclaren Spark Plugs are also 1 step colder to help prevent pre-ignition in engines that are making more power than stock allowing you to further push the envelope of your vehicle.

Key Features:

  • Higher Output for High Boost Applications

  • Colder range for better performance with increased horsepower levels

  • Direct replacement / bolt in for M838T and M840T engines

  • Suitable for all M838T and M840T vehicles from stock to highly modified

  • Set of 8

* Important: Please be sure to check and set spark plug gap prior to installation.
